h1. Autoyast based unattended installation 

 h2. Media notes 

 Installation media can be accessed via nfs,ftp or http. The path to the installation media differs from SLES9 and SLES10/11. So you have to create two separate installation media entries in foreman. 

 h3. SLES9 

 ftp://server/SLES/$major.$minor_$arch 

 h3. SLES10/11 

 ftp://server/SLES/$major.$minor_$arch/CD1 

 h2. Autoyast files 

 The Yast2 provisioning templates provided by foreman are working fine for OpenSUSE but not really for SLES. Below is a complete provisioning template tested on SLES 11.1. 

 h2. Puppet Version 

 The included version of puppet is way to old, even on SLES 11.1. One way to install a more recent version is to download a patch from Novell's website. The patch can be put on a additional installation source and included in the installation process. 

 h3. SLES 11 

 Download the patch from Novell's website. Please note that you need a valid support contract to download the patch. Create a minimal installation source that can be added during the installation process. This will ensure that a later version of puppet is installed during deployment with foreman. You can find very good instructions on how to create an installation source here: 

 http://en.opensuse.org/SDB:Creating_YaST_installation_sources#repomd.2Frpm_md.2FYUM_sources 

 Once you have the install source ready, create a new provision template in forman: 

 Name: YaST2 SLES 11.1 Repos 
 Snippet: YES 

 <pre> 
     <listentry> 
       <media_url>ftp://server/SLES/11.1_Updates/</media_url> 
       <product>VEGA</product> 
       <product_dir>/</product_dir> 
     </listentry> 
 </pre> 

 h2. h2 Additional installation sources e.g. SDK 

 Many important packages are not included in the default installation media. In case you would like to add the SDK (Software Development Kit) install sources create another provision template. 

 Name: YaST2 SLES 11.1 SDK 
 Snippet: YES 

 <pre> 
     <listentry> 
       <media_url>ftp://server/SLES/11.1_SDK/</media_url> 
       <product>VEGA</product> 
       <product_dir>/</product_dir> 
     </listentry> 
 </pre> 

 h2 Provisioning template 
 A good and minimal provisioning template tested on SLES 11.1:
