Software and Hardware Requirements
This table shows the software and hardware requirements for installing a Uyuni Server on openSUSE Leap.
Table 1. Software and Hardware Requirements

Install Uyuni Server on openSUSE Leap
You can use a physical or virtual machine running openSUSE Leap to install the Uyuni Server. Configure a resolvable fully-qualified domain name on the server before you  egin, to ensure that the server is accessible across the network.
The Uyuni Server software is available from download.opensuse.org, and you can use zypper to retrieve the software and install it.
Procedure: Installing openSUSE Leap with Uyuni

1. Install openSUSE Leap as the base system, and ensure all available service packs and package updates have been applied.

2. Configure a resolvable fully qualified domain name (FQDN) with YaST by navigating to System › Network Settings › Hostname/DNS.

3. At the command prompt, as root, add the repository for installing the Uyuni Server software:
   repo=repositories/systems management:/
   repo=${repo}Uyuni:/Stable/images/repo/Uyuni-Server-POOL-x86_64-Media1/
   zypper ar https://download.opensuse.org/$repo uyuni-server-stable

4. Refresh metadata from the repositories: zipper ref

5. . Install the pattern for the Uyuni Server: zypper in patterns-uyuni_server

6. Reboot the server.
   When the installation is complete, you can continue with the Uyuni setup. For more information, see Installation › Uyuni-server-setup.

Set up Uyuni Server with YaST
The initial setup procedure is handled by YaST.
Procedure: Uyuni Setup

1. Log in to the Uyuni Server and start YaST.

2. In YaST, navigate to Network Services › Uyuni Setup to begin the setup

3. From the introduction screen select Uyuni Setup › Set up Uyuni from scratch and click [Next] to continue.

4. Enter an email address to receive status notifications and click [Next] to continue. Uyuni can sometimes send a large volume of notification emails. You can disable email notifications in the Web UI after setup, if you need to.

5. Enter your certificate information and a password. Passwords must be at least seven characters in length, and must not contain spaces, single or double quotation marks (‘ or “), exclamation marks ( !), or dollar signs ($). Always store your passwords in a secure location.
     If you need to also set up a Uyuni Proxy Server, ensure you have taken note of the certificate password.

6. Click [Next] to continue.

7. From the Uyuni Setup › Database Settings screen, enter a database user and password and click [Next] to continue. Passwords must be at at least seven characters in length, and must not contain spaces, single or double quotation marks (‘ or “), exclamation marks (!), or dollar signs ($). Always store your passwords in a secure location.

10. When setup is complete, click [Next] to continue. You will see the address of the Uyuni Web UI.

11. Click [Finish] to complete the Uyuni setup.

Create the Main Administration Account
Before you can log in to the server to manage your clients, you need to have created an administrator account. The main administration account has the highest authority within yuni. Ensure you keep access information for this account secure. We recommend that you create lower-level administration accounts for organizations and groups. Do not hare the main administration access details.
Procedure: Setting Up the Main Administration Account

1. In your web browser, enter the address for the Uyuni Web UI. This address was provided after you completed the setup.
2. Sign in to the Web UI, navigate to the Create Organization › Organization Name field, and enter your organization name.
3. In the Create Organization, › Desired Login, and Create Organization › Desired Password fields, enter your username and password.
4. Fill in the account information fields, including an email for system notifications.
5. Click [Create Organization] to finish creating your administration account.

When you have completed the Uyuni Web UI set up, you are taken to the Home › Overview page.=
Optional: Synchronizing Products from SUSE Customer Center
SUSE Customer Center (SCC) maintains a collection of repositories that contain packages, software, and updates for all supported enterprise client systems. These repositories are organized into channels each of which provides software specific to a distribution, release, and architecture. After synchronizing with SCC, clients can receive updates, be organized into groups, and be assigned to specific product software channels.
This section covers synchronizing with SCC from the Web UI and adding your first client channel.
For Uyuni, synchronizing products from SUSE Customer Center is optional. Before you can synchronize software repositories with SCC, you will need to enter the organization credentials in Uyuni. The organization credentials give you access to the SUSE product downloads. You will find your organization credentials at https://scc.suse.com/organizations.
Enter your organization credentials in the Uyuni Web UI: Optional Procedure: Entering Organization Credentials

1. In the Uyuni Web UI, navigate to Admin › Setup Wizard.
2. On the Setup Wizard page, navigate to the [Organization Credentials] tab.
3. Click [Add a new credential].
4. Enter a username and password, and click [Save].

A check mark icon is shown when the credentials are confirmed. When you have successfully entered the new credentials, you can synchronize with SUSE Customer Center.
Optional Procedure: Synchronizing with SUSE Customer Center

1. In the Uyuni Web UI, navigate to Admin › Setup Wizard.
2. From the Setup Wizard page select the [SUSE Products] tab. Wait a moment for the products list to populate. If you previously registered with SUSE Customer Center a list of products will populate the table. This table lists architecture, channels, and status information.
3. If your SUSE Linux Enterprise client is based on x86_64 architecture scroll down the page and selects the check box for this channel now.
4. Add channels to Uyuni by selecting the check box to the left of each channel. Click the arrow symbol to the left of the description to unfold a product and list available modules.
5. Click [Add Products] to start product synchronization.

When a channel is added, Uyuni will schedule the channel for synchronization. Depending on the number and size of these channels, this can take a long time. You can monitor synchronization progress in the Web UI. For more information about using the setup wizard, see Reference › Admin. When the channel synchronization process is complete, you can register and configure clients. For more instructions, see Client-configuration › Registration-overview.

Install Uyuni Proxy with openSUSE Leap
Uyuni Proxy can be installed as a server extension on openSUSE Leap. The proxy is installed in the same way as a client, but is designated as a proxy server during installation. This is achieved by adding the Uyuni Proxy pattern and executing the proxy setup script.

• For more information about the stable version of Uyuni, see https://www.uyuni-project.org/pages/stable-version.html.
• For more information about the development version of Uyuni, see https://www.uyuni-project.org/pages/devel-version.html.

Mirror Uyuni Proxy software
The Uyuni Proxy software is available from https://download.opensuse.org. You can synchronize the proxy software to your Uyuni Server. This process is also known as mirroring. Procedure: Mirroring Uyuni Proxy software

1. On the Uyuni Server, create openSUSE Leap and the Uyuni Proxy channels with the spacewalk common-channels command. spacewalk-common-channels is part  of the
   space walkutils package:
   spacewalk-common-channels \
   opensuse_leap15_2 \
   opensuse_leap15_2-non-oss \
   opensuse_leap15_2-non-oss-updates \
   opensuse_leap15_2-updates \
   opensuse_leap15_2-Uyuni-client \
   Uyuni-proxy-stable-leap-152

Register the openSUSE Leap system
Begin by installing openSUSE Leap on a physical or virtual machine. To ensure that the proxy is accessible across the network, you must have a resolvable fully-qualified domain name (FQDN) on the openSUSE Leap system before you begin the installation. You can configure an FQDN with YaST by navigating to System › Network Settings ›ostname/DNS. When you have installed openSUSE Leap on the proxy and configured the FQDN, you can prepare the Uyuni Server, and register the openSUSE Leap system client.
Procedure: Registering the openSUSE Leap system

1. On the Uyuni Server, create an activation key with openSUSE Leap as a base channel and the proxy and the other channels as child channels. For more information about activation keys, see Client- configuration › Activation-keys.
2. Modify a bootstrap script for the proxy. Ensure you add the GPG key for Uyuni to the ORG_GPG_KEY= parameter. For example: ORG_GPG_KEY=uyuni-gpg-pubkey-0d20833e.key For more information, see xref:client-configuration:clients-OpenSUSE.adoc[].
3. Bootstrap the client using the script. For more information, see Client-configuration › Registration-bootstrap.
4. Navigate to Salt › Keys and accept the key. When the key is accepted, the new proxy will show in Systems › Overview in the Recently Registered Systems section.
5. Navigate to System Details › Software › Software Channels, and check that the proxy channel is selected.

Install Uyuni Proxy on openSUSE Leap
On the client, use the zypper command line tool or on the Uyuni Server, the Web UI to install the proxy software on openSUSE Leap.
Procedure: Installing Uyuni Proxy on openSUSE Leap

1. Install the pattern for the Uyuni Proxy. You can do this either on the client or on the server.
   ◦ For the client, use a zipper
   in patterns-uyuni_proxy
   • Alternatively, on the Uyuni Server, use the Web UI. Navigate to the details tab of the client, click Software › Packages › Install, and schedule patterns- uyuni_proxy for installation. 1. Reboot the client.

Prepare the Proxy
Before you begin, ensure that the proxy pattern is installed correctly. To verify a successful installation, on the Uyuni Server, select the pattern_uyuni_proxy package for installation.
The salt-broker service is automatically started after installation is complete. This service forwards the Salt interactions to the Uyuni Server.
It is possible to arrange Salt proxies in a chain. In this case, the upstream proxy is named parent.
Make sure the TCP ports 4505 and 4506 are open on the proxy. The proxy must be able to reach the Uyuni Server or a parent proxy on these ports.
The proxy shares some SSL information with the Uyuni Server. You need to copy the certificate and its key from the Uyuni Server or the parent proxy to the proxy you are setting up.
Procedure: Copying the Server Certificate and Key

1. On the proxy, you are setting up, at the command prompt, as root, create a directory for the certificate and key:
   mkdir -m 700 /root/ssl-build cd /root/ssl-build

2. Copy the certificate and the key from the source to the new directory. In this example, the source location is called PARENT. Replace this with the correct path:
   scp root@:/root/ssl-build/RHN-ORG-PRIVATE-SSL-KEY.
   scp root@:/root/ssl-build/RHN-ORG-TRUSTED-SSL-CERT.
   SCP root@:/root/ssl-build/rhn-ca-OpenSSL.cnf .

To keep the security chain intact, the Uyuni Proxy functionality requires the SSL certificate to be signed by the same CA as the Uyuni Server certificate. Using certificates signed by different CAs for proxies and servers is not supported. For more information on how Uyuni handles certificates, see Administration ›  slcerts .
Set Up the Proxy
When you have prepared the proxy, use the supplied interactive configure- proxy.sh script to complete the proxy setup.
Procedure: Setting up the Proxy

1. On the proxy you are setting up, at the command prompt, as root, execute the setup script: configure-proxy.sh
2. Follow the prompts to set up the proxy. Leave a field blank and type Enter to use the default values shown between square brackets.
   More information about the settings set by the script:

Uyuni Parent
the Uyuni parent can be either another proxy or a server.
HTTP Proxy
An HTTP proxy enables your Uyuni Proxy to access the Web. This is needed if direct access to the Web is prohibited by a firewall.
Traceback Email
An email address where to report problems.
Do You Want to Import Existing Certificates?
Answer N. This ensures using the new certificates that were copied previously from the Uyuni server. Organization
The next questions are about the characteristics to use for the SSL certificate of the proxy. The organization might be the same organization that was used on the server unless of course, your proxy is not in the same organization as your main server. Organization Unit
The default value here is the proxy’s hostname.
City
Further information is attached to the proxy’s certificate.
State
Further information is attached to the proxy’s certificate.
Country Code
In the country code field, enter the country code set during the Uyuni installation. For example, if your proxy is in the US and your Uyuni is in DE, enter DE for the proxy.
The country code must be two upper case letters. For a complete list of country codes, see https://www.iso.org/obp/ui/#search.
Cname Aliases (Separated by Space)
Use this if your proxy can be accessed through various DNS CNAME aliases. Otherwise, it can be left empty.
CA Password
Enter the password that was used for the certificate of your Uyuni Server.
Do You Want to Use an Existing SSH Key for Proxying SSH-Push Salt Minion?
Use this option if you want to reuse an SSH key that was used for SSH-Push Salt clients on the server.
Create and Populate Configuration Channel rhn_proxy_config_1000010001?
Accept default Y.
SUSE Manager Username
Use the same user name and password as on the Uyuni server.
If parts are missing, such as the CA key and public certificate, the script prints commands that you must execute to integrate the needed files. When the mandatory files are copied, unconfigure-proxy.sh again.
If you receive an HTTP error during script execution, run the script again. configure-proxy.sh activates services required by Uyuni Proxy, such as squid, apache2, sale broker, and jabbered.
To check the status of the proxy system and its clients, click the proxy system’s details page on the Web UI (Systems › System List › Proxy, then the system name). Connection and Proxy subtabs display various status information.
If you want to PXE boot your clients from your Uyuni Proxy, you also need to synchronize the TFTPdata from the Uyuni Server. For more information about this synchronization, see Client-configuration › Autoinst-pxeboot.
Procedure: Synchronizing Profiles and System Information

1. On the proxy, at the command prompt, as root, install the susemanager-FTP sync-recv package: zipper in SUSE manager-FTP sync-recv
2.  On the proxy, run the configure-tftpsync. sh setup script and enter the requested information: configure-tftpsync.sh You need to provide the hostname and IP address of the Uyuni Server and the proxy. You also need to enter the path to the tftpboot directory on the proxy.
3. On the server, at the command prompt, as root, install SUSE manager-FTP sync  zipper in SUSE manager-tftpsync
4. On the server, run configure-FTP sync.sh setup script and enter the requested information: configure-tftpsync. sh
5.  Run the script again with the fully-qualified domain name of the proxy you are setting up. This creates the configuration and uploads it to the Uyuni Proxy: configure-tftpsync.sh FQDN_of_Proxy
6. On the server, start an initial synchronization: cobbler sync
   You can also synchronize after a change within Cobbler that needs to be synchronized immediately. Otherwise, Cobbler synchronization will run automatically when needed. For more information about PCE booting, see Client- configuration › Autoinst-pxeboot.

Configure DHCP for PXE through Proxy
Uyuni uses Cobbler for client provisioning. PXE (TFTP) is installed and activated by default. Clients must be able to find the PXE boot on the Uyuni Proxy using DHCP. Use this HCP configuration for the zone which contains the clients to be provisioned:
next-server:   filename: “pxelinux.0”
Reinstalling a Proxy
A proxy does not contain any information about the clients that are connected to it. Therefore, a proxy can be replaced by a new one at any time. The replacement proxy must have the same name and IP address as its predecessor.
For more information about reinstalling a proxy, see Installation › Proxy- setup.Proxy systems are registered as Salt clients using a bootstrap script.
This procedure describes software channel setup and registering the installed proxy with an activation key as the Uyuni client.

Before you can select the correct child channels while creating the activation key, ensure you have properly synchronized the openSUSE Leap channel with all the needed child channels and the Uyuni Proxy channel.

PREAMBLE
The purpose of this License is to make a manual, textbook, or another functional and useful document “free” in the sense of freedom: to assure everyone the effective freedom to copy and redistribute it, with or without modifying it, either commercially or noncommercially. Secondarily, this License preserves for the author and publisher a way to get credit for their work, while not being considered responsible for modifications made by others
. This License is a kind of “copyleft”, which means that derivative works of the document must themselves be free in the same sense. It complements the GNU General Public License, which is a copyleft license designed for free software.
We have designed this License in order to use it for manuals for free software because free software needs free documentation: a free program should come with manuals providing the same freedoms that the software does. But this License is not limited to software manuals; it can be used for any textual work, regardless of subject matter or whether it is published as a printed book. We recommend this License principally for works whose purpose is instruction or reference.

APPLICABILITY AND DEFINITIONS

This License applies to any manual or other work, in any medium, that contains a notice placed by the copyright holder saying it can be distributed under the terms of this License. Such a notice grants a worldwide, royalty-free license, unlimited in duration, to use that work under the conditions stated herein. The “Document”, below, refers to any such manual or work. Any member of the public is a licensee, and is addressed as “you”. You accept the license if you copy, modify or distribute the work in a way requiring permission under copyright law.
A “Modified Version” of the Document means any work containing the Document or a portion of it, either copied verbatim or with modifications and/or translated into another language.
A “Secondary Section” is a named appendix or a front-matter section of the Document that deals exclusively with the relationship of the publishers or authors of the Document to the Document’s overall subject (or to related matters) and contains nothing that could fall directly within that overall subject. (Thus, if the Document is in part a textbook of mathematics, a Secondary Section may not explain any mathematics.) The relationship could be a matter of historical connection with the subject or with related matters, or of legal, commercial, philosophical, ethical or political position regarding them.
The “Invariant Sections” are certain Secondary Sections whose titles are designated, as being those of Invariant Sections, in the notice that says that the Document is released under this License. If a section does not fit the above definition of Secondary then it is not allowed to be designated as Invariant. The Document may contain zero Invariant Sections. If the Document does not identify any Invariant Sections then there are none.
The “Cover Texts” are certain short passages of text that are listed, as Front-Cover Texts or Back-Cover Texts, in the notice that says that the Document is released under this License. A Front-Cover Text may be at most 5 words, and a Back-Cover Text may be at most 25 words.
A “Transparent” copy of the Document means a machine-readable copy, represented in a format whose specification is available to the general public, that is suitable for revising the document straightforwardly with generic text editors or (for images composed of pixels) generic paint programs or (for drawings) some widely available drawing editor, and that is suitable for input to text formatters or for automatic translation to a variety of formats suitable for input to text formatters.
A copy made in an otherwise Transparent file format whose markup, or absence of markup, has been arranged to thwart or discourage subsequent modification by readers is not Transparent. An image format is not Transparent if used for any substantial amount of text. A copy that is not “Transparent” is called “Opaque”. Examples of suitable formats for Transparent copies include plain ASCII without markup, Texinfo input format, LaTeX input format, SGML or XML using a publicly available DTD, and standard-conforming simple HTML, PostScript or PDF designed for human modification. Examples of transparent image formats include PNG, XCF and JPG. Opaque formats include proprietary formats that can be read and edited only by proprietary word processors, SGML or XML for which the DTD and/or processing tools are not generally available, and the machine-generated HTML, PostScript or PDF produced by some word processors for output purposes only.
The “Title Page” means, for a printed book, the title page itself, plus such following pages as are needed to hold, legibly, the material this License requires to appear in the title page. For works in formats that do not have any title page as such, “Title Page” means the text near the most prominent appearance of the work’s title, preceding the beginning of the body of the text. A section “Entitled XYZ” means a named subunit of the Document whose title either is precisely XYZ or contains XYZ in parentheses following text that translates XYZ in another language. (Here XYZ stands for a specific section name mentioned below, such as “Acknowledgements”, “Dedications”, “Endorsements”, or “History”.) To “Preserve the Title” of such a section when you modify the Document means that it remains a section “Entitled XYZ” according to this definition.
The Document may include Warranty Disclaimers next to the notice which states that this License applies to the Document. These Warranty Disclaimers are considered to be included by reference in this License, but only as regards disclaiming warranties: any other implication that these Warranty Disclaimers may have is void and has no effect on the meaning of this License.

VERBATIM COPYING

You may copy and distribute the Document in any medium, either commercially or noncommercially, provided that this License, the copyright notices, and the license notice  saying this License applies to the Document are reproduced in all copies, and that you add no other conditions whatsoever to those of this License. You may not use technical measures to obstruct or control the reading or further copying of the copies you make or distribute. However, you may accept compensation in exchange for copies. If you distribute a large enough number of copies you must also follow the conditions in section 3.  You may also lend copies, under the same conditions stated above, and you may publicly display copies.

COPYING IN QUANTITY

If you publish printed copies (or copies in media that commonly have printed covers) of the Document, numbering more than 100, and the Document’s license notice requires Cover Texts, you must enclose the copies in covers that carry, clearly and legibly, all these Cover Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on the back cover. Both covers must also clearly and legibly identify you as the publisher of these copies. The front cover must present the full title with all words of the title equally prominent and visible. You may add other material on the covers in addition. Copying with changes limited to the covers, as long as they preserve the title of the Document and satisfy these conditions, can be treated as verbatim copying in other respects.
If the required texts for either cover are too voluminous to fit legibly, you should put the first ones listed (as many as fit reasonably) on the actual cover, and continue the rest onto adjacent pages.
If you publish or distribute Opaque copies of the Document numbering more than 100, you must either include a machine-readable Transparent copy along with each Opaque opy, or state in or with each Opaque copy a computer-network location from which the general network-using public has access to download using public-standard network protocols a complete Transparent copy of the Document, free of dded material. If you use the latter option, you must take reasonably prudent steps, when you begin distribution of Opaque copies in quantity, to ensure that this Transparent copy will remain thus accessible at the stated location until at least one year after the last time you distribute an Opaque copy (directly or through your agents or retailers) of that edition to the public. It is requested, but not required, that you contact the authors of the Document well before redistributing any large number of copies, to give them a chance to provide you with an updated version of the Document.

MODIFICATIONS

You may copy and distribute a Modified Version of the Document under the conditions of sections 2 an3 above, provided that you release the Modified Version under precisely this License, with the modified version filling the role of the Document, thus licensing distribution and modification of the ModifieVersion to whoever possesses a copy of it. In addition, you must do these things in the Modified Version:

A. Use in the Title Page (and on the covers, if any) a title distinct from that of the Document, and from those of previous versions (which should, if there were any, be listed in the History section of the document). You may use the same title as a previous version if the original publisher of that version gives permission.
B. List on the Title Page, as authors, one or more persons or entities responsible for authorship of modifications in the Modified Version, together with at least five of the principal authors of the document (all of its principal authors, if it has fewer than five), unless they release you from th requirement.
C. State on the Title page the name of the publisher of the Modified Version, as the publisher.
D. Preserve all the copyright notices of the Document. E. Add an appropriate copyright notice for your modifications adjacent to the other copyright notices.
F. Include, immediately after the copyright notices, a license notice giving the public permission to use the Modified Version under the terms of this License, in the form shown in the Addendum below.
G. Preserve in that license notice the full lists of Invariant Sections and required Cover Texts given in the Document’s license notice.
H. Include an unaltered copy of this License.
I. Preserve the section Entitled “History”, Preserve its Title, and add to it an item stating at least the title, year, new authors, and publisher of the Modified Version as given on the Title Page. If there is no section Entitled “History” in the Document, create one stating the title, year, authors, and publisher of the Document as given on its Title Page, then add an item describing the Modified Version as stated in the previous sentence.
J. Preserve the network location, if any, given in the Document for public access to a Transparent copy of the Document, and likewise the network locations given in the Document for previous versions it was based on. These may be placed in the “History” section. You may omit a network location for a work that was published at least four years before the Document itself, or if the original publisher of the version it refers to gives permission.
K. For any section Entitled “Acknowledgements” or “Dedications”, Preserve the Title of the section, and preserve in the section all the substance and tone of each of the contributor acknowledgments and/or dedications given therein.
L. Preserve all the Invariant Sections of the Document, unaltered in their text and in their titles. Section numbers or the equivalent are not considered part of the section titles. M. Delete any section Entitled “Endorsements”. Such a section may not be included in the Modified Version.
N. Do not retitle any existing section to be Entitled “Endorsements” or to conflict in title with any Invariant Section. O. Preserve any Warranty Disclaimers.
If the Modified Version includes new front-matter sections or appendices that qualify as SecondarySections and contain no material copied from the Document, you may at our  option designate some orll of these sections as invariant. To do this, add their titles to the list of Invariant Sections in the Modified Version’s license notice. These titles must  e distinct from any other section titles. You may add a section Entitled “Endorsements”, provided it contains nothing but endorsements of your Modified Version by various parties—for example, statements of peer review or that the text has been approved by an organization as the authoritative definition of a standard.
You may add a passage of up to five words as a Front-Cover Text, and a passage of up to 25 words as aBack-Cover Text, to the end of the list of Cover Texts in the Modified version. Only one passage of Front-Cover Text and one of Back- Cover Text may be added by (or through arrangements made by) any one entity. If the Document already ncludes a cover text for the same cover, previously added by you or by arrangement made by the same entity you are acting on behalf of, you may not add another; but you may place the old one, on explicit permission from the previous publisher that added the old one.
The author(s) and publisher(s) of the Document do not by this License give permission to use their names for publicity for or to assert or imply endorsement of any Modified Version.

COMBINING DOCUMENTS

You may combine the Document with other documents released under this License, under the terms defined in section 4 above for modified versions, provided that you include n the combination all of the Invariant Sections of all of the original documents, unmodified, and list them all as Invariant Sections of your combined work in its license notice, and that you preserve all their Warranty Disclaimers.
The combined work need only contain one copy of this License, and multiple identical Invariant Sections may be replaced with a single copy. If there are multiple Invariant sections with the same name but different contents, make the title of each such section unique by adding at the end of it, in parentheses, the name of the original author or publisher of that section if known, or else a unique number. Make the same adjustment to the section titles in the list of Invariant Sections in the license notice of the combined work. the combination, you must combine any sections Entitled “History” in the various original documents, forming one section Entitled “History”; likewise combine any sections Entitled “Acknowledgements”, and any sections Entitled “Dedications”. You must delete all sections Entitled “Endorsements”.

COLLECTIONS OF DOCUMENTS

You may make a collection consisting of the Document and other documents released under this License,and replace the individual copies of this License in the various documents with a single copy that is included in the collection, provided that you follow the rules of this License for verbatim copying of each of the documents in all other respects. You may extract a single document from such a collection, and distribute it individually under this license, provided you insert a copy of this License into the extracted document and follow this License n all other respects regarding verbatim copying of that document.
AGGREGATION WITH INDEPENDENT WORKS
A compilation of the Document or its derivatives with other separate and independent documents or works, in or on a volume of a storage or distribution medium, is called an aggregate” if the copyright resulting from the compilation is not used to limit the legal rights of the compilation’s users beyond what the individual works permit. When the document is included in an aggregate, this License does not apply to the other works in the aggregate which are not themselves derivative works of the Document.
If the Cover Text requirement of section 3 is applicable to these copies of the Document, then if the document is less than one-half of the entire aggregate, the Document’s  Cover Texts may be placed on covers that bracket the Document within the aggregate, or the electronic equivalent of covers if the Document is in electronic form. Otherwise hey must appear on printed covers that bracket the whole aggregate.

**TRANSLATION

**

The translation is considered a kind of modification, so you may distribute translations of the Document under the terms of section 4. Replacing Invariant Sections with translations requires special permission from their copyright holders, but you may include translations of some or all Invariant Sections in addition to the original versions of these Invariant Sections. You may include a translation of this License, and all the license notices in the Document, and any Warranty Disclaimers, provided that you also include
the original English version of this License and the original versions of those notices and disclaimers. In case of a disagreement between the translation and the original version of this License or a notice or disclaimer, the original version will prevail.
If a section in the Document is Entitled “Acknowledgements”, “Dedications”, or “History”, the requirement (section 4) to Preserve its Title (section 1) will typically require changing the actual title.
