It doesn't really involve much. You can mostly follow Helge's instructions from [1]. You don't need to build debian-installer manually and you don't need to include the bootloader installers manually. Just create a local repository copy of Debian Ports with reprepro and make sure you include both unstable and unreleased. Then edit CONF.sh and easy-build.sh to work with Debian Ports and your local mirror paths. You can just use script versions attached to this mail, just edit "MIRROR", "OUT" and "APTTMP" in CONF.sh to match your personal setup. In easy-build.sh, you also must set the path to where the debian-installer images can be found, e.g.: export DI_DIR="/home/glaubitz/d-i/%ARCH%/installer-%ARCH%/current/images/" I usually build current d-i images locally (natively or with qemu-user), then copy the resulting tarball into /home/glaubitz/d-i on the CD building machine and extract the tarball there which includes the folder installer-$ARCH. You just have to make sure the kernel packages that are in your local repo have the same _ABI_ (not kernel) version as the kernel in the debian-installer you are using. For example, if you have "linux-image-5.9.0-2-powerpc_5.9.6-1_powerpc.deb" in the mirror in $MIRROR/debian-ports/pool-powerpc/main/l/linux/, then debian-installer must have been built with "LINUX_KERNEL_ABI ?= 5.9.0-2" in build/config/common. You can just build debian-installer locally with a regular sbuild setup. Then build an image with: # ./easy-build-ports.sh NETINST powerpc # or whatever arch you want That's it. If you run into any problems, let me know and I'll help you. Oh, and for m68k, you need to use genisoimage from cdrkit instead of xorriso since the latter does not support legacy HFS filesystems yet (also something that I would like to see fixed upstream): export MKISOFS="xorriso" export MKISOFS_OPTS="-as mkisofs -r -checksum_algorithm_iso md5,sha256,sha512" export m68k_MKISOFS="genisoimage" export m68k_MKISOFS_OPTS="-r -checksum_algorithm_iso md5,sha256,sha512" Adrian > [1] https://parisc.wiki.kernel.org/index.php/How_to_create_Debian_unstable_iso_images -- .''`.
