Build a root filesystem for each architecture and run genimage's selection over
it, so the riscv64 libraries are taken from their own directory and the other
architectures keep the files they take today.

Pin the kernel and initrd the riscv64 live image carries, that the kernel name
the other live images use is not accepted for it, and that the architecture the
media reports maps to riscv64 in both directions.

Both scripts run for real with PATH holding one directory that carries a
tcpdump stand-in, which records the path and arguments it was started with.
The plain run stops at the interface step, before any socket or capture. The
capture runs inside a private network and mount namespace, where the loopback
interface is the only one, its default route keeps the DHCP discover on the
host, a tmpfs over /tmp holds the dump file, and /usr/sbin/tcpdump is hidden
so the previous guard fails there on every host. Hosts that cannot create the
namespace skip that part.
The lists are resolved through get_pkglist_file_name, the resolver that picks
one for an osimage, and read through get_pkglist_tex, the parser that
produces OSPKGS. 59 of 94 assertions fail against the previous lists: the dead
names, the missing 26.04 lists, unixodbc, qemu-utils and libvirt packages,
and every kvm osimage resolving to the shared list with the old emulator.
The check functions and the installer functions that call them are taken
from the shipped script and run against a dnf stand-in that records its
probes. 27 of 40 assertions fail against the previous
script: EL10 and CentOS Stream were not checked, the probe went through dnf
list, a failed query read as a missing repository, and the CRB message
carried a repository file with signature checks disabled.
Drive the assignment genimage makes and check the name debootstrap receives for
each architecture, including the POWER LE spelling that debootstrap rejects.
Pin both directions for every architecture xCAT supports on Ubuntu, the
pass-through for names Debian shares, and the round trip that copycd and
debootstrap depend on agreeing about.
Build each Ubuntu media layout on disk and ask the resolver for its kernel and
initrd: the netboot trees, the flat netboot layout, both casper images, and the
POWER layouts where the kernel and the initrd sit in different directories.
Pin the precedence the installer depends on, a netboot tree over a live image
and a hardware-enablement kernel over the release one, and pin the three ways
media resolve to nothing.
getipaddr answers from %::hostiphash before it resolves. The bypass tests
OnlyV6 and GetAllAddresses and does not test OnlyV4, so a caller that asks for
IPv4 is handed whatever the first lookup cached.
An unrestricted lookup passes AF_UNSPEC to getaddrinfo, so on a dual-stack
management node with an AAAA record it caches the IPv6 address. xcatd is
long-lived and the hash is a global, so one earlier caller poisons every OnlyV4
caller after it.
debian.pm then writes nfsroot=2001:db8::1:/install, which is not a parseable
nfsroot, and the Subiquity install never mounts. dhcp.pm and mknb.pm hold four
more OnlyV4 callers with the same exposure.
The test also pins what the fix must not break: an IPv4 cache entry is still
served to an OnlyV4 caller, and an unrestricted caller still gets its cache hit
whatever family it holds.
