reg_linux_diskfull_installation_flat fails on every ppc64le cell of xcat-core-devel-ubuntu-cd. nodeset stops before it writes a grub2 entry (build #119, ubuntu-24-ppc64le-devel): xcat25-cn: The network boot initrd.gz is not found in /install/ubuntu24.04.4/ppc64el/install/netboot. The Ubuntu ppc64el live-server ISO carries no netboot tree. It keeps the installer kernel and initrd under casper: 22.04 and 24.04 ship hwe-vmlinux and hwe-initrd beside vmlinux and initrd, 26.04 ships the release pair only. %INSTALL_BOOT_FILES describes that layout for x86 and not for POWER, and mkinstall carries a second, POWER-only precondition on install/netboot/initrd.gz that no live image satisfies. The new cases resolve the POWER casper layouts, and ask a single routine whether media is bootable. They fail now. Signed-off-by: Daniel Hilst <392820+dhilst@users.noreply.github.com>
