Hi debian-s390, As far as I learnt from the debian-s390 archive, mainframes 'prefer' to boot using kernel image (kernel.debian, initrd.debian) rather than from ISO/CD images.
I would like to learn the code that build up these kernel & initrd image files, which are located at http://ftp.nl.debian.org/debian/dists/stable/main/installer-s390x/current/images/generic/. If the code is publicly accessible, where should I can find them ? I guess the code shares some similarities with those building ISO images on other arch but I don't even know where to get them neither. Thanks, Tuan
