Customization of the UCS install DVD
From Univention Wiki
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 xorriso
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 -> /opt/cd.new/packages/
- new installation profiles -> /opt/cd.new/profiles/
- grub configuration -> /opt/cd.new/boot/grub/grub.cfg
- additional ucs installer scripts -> /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 ./ >Packages && gzip -c Packages >Packages.gz if [ -d dists/univention/main/binary-i386 ]; then apt-ftparchive packages ./ >dists/univention/main/binary-i386/Packages gzip -c dists/univention/main/binary-i386/Packages >dists/univention/main/binary-i386/Packages.gz fi if [ -d dists/univention/main/binary-amd64 ]; then apt-ftparchive packages ./ >dists/univention/main/binary-amd64/Packages gzip -c dists/univention/main/binary-amd64/Packages >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
