The Subiquity diskful path builds three values from configuration, and nothing checks that the value it builds is one the consumer can use. The boot flip addresses port 3002. xcatd's install monitor listens on site.xcatiport, so a cluster that moves the port loses the flip and every node PXE-loops. The exchange also counts any reply as an accepted request, so a different service on that port reads as a flipped node. xcatd greets with "ready" and answers every request with "done". subiquity_nfsroot_server resolves the install server without a family. A dual-stack management node answers with its IPv6 address, and nfsroot=<v6>:<path> is unparseable, because klibc nfsmount takes everything after the first colon as the path. The DNS setup writes the xcatmaster name as a nameserver when getent fails, which is the case the step exists to prevent. ubuntu_subiquity_boot_flip.t drives the template's own late-command against a stand-in monitor. ubuntu_resolvconf_ip.t runs the DNS step and reads the file it writes. debian_subiquity_boot_params.t drives the helpers with a dual-stack resolver. All three fail on this commit. Signed-off-by: Daniel Hilst <392820+dhilst@users.noreply.github.com>
