Customization of the UCS install DVD
From Univention Wiki
This article provides a short description about how to customize an ISO image of a UCS installation DVD.
The best platform to customize a UCS install DVD is the corresponding UCS system. The following software packages need to be installed:
univention-install grub-common apt-utils xorriso
To customize a UCS install DVD image, the content of the ISO image file or the DVD has to be copied in a new local directory. The example assumes the content at /cdrom. The ISO image needs to be mounted to this location with mount -o loop /isofile /cdrom.
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 customizations are possible:
- Provide new or updated packages → /opt/cd.new/packages/
- Provide new installation profiles → /opt/cd.new/profiles/
- Provide a customized grub configuration → /opt/cd.new/boot/grub/grub.cfg
- Add 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
