reg_linux_diskfull_installation_flat fails on ubuntu-22-ppc64le-devel and ubuntu-24-ppc64le-devel in build #121 of xcat-core-devel-ubuntu-cd. The Subiquity installer starts, errors in its early-commands, tars /var/log/installer to port 8080 and reboots, nine times in 75 minutes. No system is ever installed, so the address answers from the live installer and the case ends on "root@xcat25-cn: Permission denied (publickey,password)". mkinstall in xCAT-server/lib/xcat/plugins/debian.pm selected pre.ubuntu.subiquity and then replaced it with pre.ubuntu.ppc64 for every ppc64 node, whichever installer was in use. pre.ubuntu.ppc64 writes a partman recipe, and the early-commands append it to /autoinstall.yaml, which Subiquity cannot parse. pre.ubuntu.subiquity offered a UEFI branch and a BIOS branch, so a ppc64el node took the BIOS branch and was given a bios_grub partition. POWER firmware loads the boot loader from a PReP partition. install_prescript now returns the script from the installer and the architecture together, and the ppc64 script is reached only on the debian-installer path. pre.ubuntu.subiquity gains a PReP branch, taken when uname reports a POWER machine, which flags an 8M first partition prep and makes that partition the grub device. debian_install_prescript.t and the PReP case of ubuntu_subiquity_storage.t fail without these changes.
