The gating reg_linux_diskfull_installation_flat case cannot pass on Ubuntu: the compute node never reaches a booted, installed OS, and the case only ever reports "ssh: connect ... port 22: Connection refused". It is not one defect but a chain, each reachable only once the one before it is fixed. The installer never boots. Without boot=casper, casper never processes netboot=nfs -- it scans the local disks, finds no live media and panics "Unable to find a medium containing a live file system". nfsroot must also be a literal IP: casper mounts the live filesystem with klibc's nfsmount, which cannot resolve a hostname. And with the NFS root still mounted at end of install, systemd-shutdown blocks forever on an lvm/pvscan wedged in uninterruptible I/O on it, so the node never power-cycles into the disk it just installed. The installer has no usable DNS. A nameserver line in /etc/resolv.conf must hold an IP -- glibc's resolver discards a hostname written there -- so writing the xcatmaster name leaves the installer, and the in-target apt that inherits the file, hanging on archive.ubuntu.com. In-target apt cannot find its packages on classic-sources releases, because Subiquity renders the target sources.list from the install media alone. The node never leaves the installer. The boot flip to local disk goes through updateflag.awk, which needs gawk's |& /inet coprocess, but Ubuntu's /usr/bin/awk is mawk -- so the flip fails silently and the node reinstalls forever. And syncfiles runs inside the in-target chroot, asking the MN to scp files into a node that has no sshd yet, so it times out and the node reports failed on a good install. Cover each stage. All fail today. Signed-off-by: Daniel Hilst <392820+dhilst@users.noreply.github.com>
