Hey all! So I am attempting to build a custom Deb12 installer where the goal is to be able to do a zerotouch install to a system (currently using preseeding) and have it set up the partitioning for an encrypted root. Normally I'd just use preseeding entirely, but partman-auto-crypto doesn't allow for setting up encryption WITHOUT the use of LVM, which I'm not allowed to use in our environment.
I had e-mailed several months ago to see about possibly updating partman-auto-crypto, but in the mean time I'm trying to get something working internally. I found https://github.com/thoto/partrep and used that as a basis for how to build a package that replaces partman, and wrote my own handling for getting things set up correctly in our environment. In running install tests with this, I can see it's successfully partitioned the root disk, set up LUKS based dm crypt on the root partition, formatted and mounted the partitions, wrote out /etc/fstab and /etc/crypttab, and queued the correct target packages. My package exits with 0 correctly. My problem comes when the next step of the installer runs, and the base-installer tries to run debootstrap. The install process freezes, then the base-installer package exits with a non-zero code. I can't seem to find any more info from it though. Interestingly, if I go into the menu and manually run base-installer again, the install completes successfully. I have gone through and extracted both the original Deb12 initrd.gz as well as my altered one and ran a diff on every file. Other than the additional files from my package, and the extra entries in /var/lib/dpkg/status for the new package and it's dependencies (bzpartrep, crypto-dm-modules, cryptsetup-udeb, di-utils-mapdevfs, disk-detect, dmidecode-udeb, dmsetup-udeb, dosfsutils-udeb, e2fsprogs-udeb, efi-modules, liibargon2-1-udeb, libcryptsetup12-udeb, libdevmapper1.02.1-udeb, libjson-c5-udeb, libparted2-udeb, libpopt0-udeb, md-modules, and parted-udeb) For reference, here is part of the debian/control file: Package: bzpartrep Package-Type: udeb Architecture: any Depends: ${shlibs:Depends}, ${misc:Depends}, e2fsprogs-udeb, dosfstools-udeb, efi-modules, archdetect, harddrive-detection, di-utils-mapdevfs, di-utils, cdebconf-udeb, cryptsetup-udeb, crypto-modules, crypto-dm-modules, parted-udeb Provides: partman-base, made-filesystems, mounted-partitions, partitioned-harddrives, created-fstab Installer-Menu-Item: 4199 Description: Encrypted partition partman alternative Any suggestions, or things I'm missing?
