View source for Customization of the UCS install DVD

The best platform to customize a ucs install dvd is the corresponding ucs system. The following software packages have to be installed. 

 grub-common
 apt-utils

The first step is to copy the install dvd content to a local directory (/cdrom can also be a iso image, then mount -o loop /isofile is required). 

 mkdir /opt/cd.new
 mount /cdrom 
 cp -a /cdrom/* /opt/cd.new/
 cp -a /cdrom/.??* /opt/cd.new/
 umount /cdrom
 chmod -R 755 /opt/cd.new

The following adjustments are possible: 

* new/updated packages -&gt; /opt/cd.new/packages/ 
* new installation profiles -&gt; /opt/cd.new/profiles/ 
* grub configuration -&gt; /opt/cd.new/boot/grub/grub.cfg 
* additional ucs installer scripts -&gt; /opt/cd.new/script/installer 

If packages are added or updated, the packages file have to be recreated: 

 cd /opt/cd.new/packages/
 apt-ftparchive packages ./ &gt;Packages &amp;&amp; gzip -c Packages &gt;Packages.gz
 if [ -d dists/univention/main/binary-i386 ]; then
     apt-ftparchive packages ./ &gt;dists/univention/main/binary-i386/Packages
     gzip -c dists/univention/main/binary-i386/Packages &gt;dists/univention/main/binary-i386/Packages.gz
 fi
 if [ -d dists/univention/main/binary-amd64 ]; then
     apt-ftparchive packages ./ &gt;dists/univention/main/binary-amd64/Packages
     gzip -c dists/univention/main/binary-amd64/Packages &gt;dists/univention/main/binary-amd64/Packages.gz
 fi

The new image can be created with the following command: 

 grub-mkrescue -o /opt/cd-new.iso /opt/cd.new
