Two independent defects stop xCAT working on Ubuntu 26.04 (resolute). bind9 is only a Recommends on the xcat and xcatsn metapackages. xCAT manages the cluster DNS through makedns/named, so a DNS server is essential to a management or a service node -- but a Recommends is installed only while the system's APT recommendation policy asks for it, so nothing guarantees named is on the node. On an Ubuntu 26.04 management node it was not there: no /usr/sbin/named, and makedns failed with "failed to start named". The Ubuntu netboot genimage reduces an osimage's osvers to a debootstrap suite with a bare s/\.\d+$//. That also strips the minor from a two-part osvers -- an initial release with no point-release ISO -- so ubuntu26.04 becomes "26" and debootstrap dies with "E: No such script: /usr/share/debootstrap/scripts/26". It is not 26.04-specific: an initial-release 18.04/20.04/22.04 ISO hits it too. Assert bind9 is a hard Depends on both metapackages, and drive genimage's real codename derivation over a table of osvers. Both fail today.
