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.

Pin the configuration symbols that let the riscv64 Genesis kernel describe
its hardware on firmware that publishes ACPI tables and no device tree, and
the EFI stub grub2 boots it through. Without them the image dies before the
console exists and the node goes silent instead of discovering.
Add a unit test for the option that selects fping instead of nmap.
The test takes the specification out of the plugin source and gives it to
Getopt::Long with the settings that the daemon uses, so it drives the
specification that the plugin ships.
It shows that -f, --usefping and the older --useping each select fping, that
--use and --us still select usemon and do not select fping, that the bundles
-mf and -fm select both options, and that both places parse through the one
specification.
Add a unit test for the routine that chooses the compression program. The
test lifts the routine out of the plugin source, because the plugin needs a
management node to load.
The test shows that lzma is used when it is there, that xz stands in when it
is not, and that xz is asked for the lzma container rather than its own. It
also shows that the caller takes the command from the routine, that the file
keeps its name and its suffix, and that the gzip fallback and the rename into
place both remain.
The install disk autotests read the log of a provisioned node. The
choice files no longer carry the identifier in their name, and the
selection message names the driver group and the identifier instead of
the previous wording, so read the new lines. The reinstall case reads
the record of its disk without naming a group, as it did before.
Cover a RAID volume that reports a WWN against a direct attached disk
that reports none, in both scan orders, which the previous readback
decided by identifier. Keep the identifier rules of one group under
test as well: the disk that reports a WWN wins, the lower WWN wins
between two, and a path wins over no identifier at all.
Cover a guest whose only disk is a Xen disk, which the scan has to
select rather than leave to the fallback, and a guest with two Xen
disks, where the driver group decides. Against the previous filter both
cases fail.
Assert that the RHEL 10 copy is gone, that the RHEL 10 installer
includes the common script, and that the common script keeps the VROC
fallback, the Xen fallback and the guarded failure log.
The RHEL 10 copy of the script is about to go away, so stop naming it
here first. The cases keep running against the common script, so the
coverage does not change.
The install disk autotest reads the log of a node whose disks sit
behind a SAS host adapter, and that driver group moved from the second
choice to the third. Read the third group instead.
Run the real scripts in a sandbox. A stub udevadm serves the device
properties from fixture files, and the partition list and the output
paths move into the sandbox. Every case runs against the common script
and against the copy the RHEL 10 installer includes.
Cover the direct attached disk against a RAID volume, a RAID only
server, the host adapter against a direct attached disk and against an
unknown driver, an NVMe device from the last group, and the default
fallback. Against the previous scripts the RAID cases fail, so they
discriminate.
