xcat-genesis-scripts-amd64 is Architecture: all, so the plain Depends installed
the x86 legacy Genesis scripts, and the x86 Genesis base with them, on a riscv64
management node. riscv64 has no legacy Genesis: its image ships as
xcat-genesis-openembedded-riscv64, which the metapackage already recommends and
mknb consumes. xCAT.spec makes the same distinction on the rpm side.
The dependency is now restricted to the architectures that have a legacy
Genesis. amd64 and ppc64el keep it unchanged.

The guides said riscv64 covered EL10 only, and the riscv64 page listed
Ubuntu as unsupported. Both support matrices now carry the architecture for
Ubuntu, and the riscv64 page describes the Ubuntu paths: the loader copycd
builds from the media, the installer needing none of the accommodations
EL10 requires, the ports archive the packages come from, and a management
node running on riscv64. The 26.04 media need the RVA23 profile, which is
recorded as a limitation.

The note shown when boot/grub2/grub2.<arch> is missing told the
administrator it comes from grub2-xcat or the EL installation media. On
Ubuntu neither is true: copycd builds the loader from the grub2 package on
the media, because the image the media carry cannot boot over the network.

The noderes.netboot table gave riscv64 the condition >=el10, so the only
documented way to reach grub2 on the architecture was an EL node, although
lookupNetboot answers grub2 for riscv64 whatever the operating system. The
condition now names Ubuntu as well, the way ppc64 names both of its
families.

go-xcat stopped on riscv64 before it reached the package manager, so the

archive.ubuntu.com publishes amd64 and i386 only, so a ppc64el or riscv64
node was given an apt mirror carrying no package for it and the installer
could not fetch what the minimal live media lacks. The default is now the
ports archive for those architectures, chosen from the osimage's
architecture rather than the package directory, which is whatever path the
administrator configured. site.ubuntu_apt_mirror still overrides it.

Calls the escaping the plugin performs. Covers the Ubuntu installer seed
keeping the arguments after it, every separator grub2 recognizes, a command
line without one staying byte for byte the same, escaped and quoted values
surviving unchanged, a separator beside a quoted span in the same word, and
a variable reference being left alone so BOOTIF still expands.

grub2 reads its configuration as a script, so an unquoted command separator
ends the linux command and everything after it is lost. The Ubuntu
installer seed is written as ds=nocloud-net;s=<url>, so the node booted
without the seed URL and without the arguments that followed it, including
BOOTIF. The installer then found no autoinstall configuration and waited
for someone to answer its questions. A separator that is neither escaped
nor inside a quoted span is now escaped where it stands, which grub2
removes before it hands the line to the kernel. A value the caller escaped
or quoted keeps exactly the form the caller gave it.

The Ubuntu driver table had no riscv64 entry, so genimage was handed an
empty list and built an image carrying no network module. A node whose NIC
is not built into the kernel then has no interface to fetch its root
filesystem with. The architecture now gets the same drivers the enterprise
Linux table lists for it, plus the overlay module every Ubuntu image needs.

Extends the builder tests with the per-package architecture lists and the

The xcat and xcatsn packages declared only amd64 and ppc64el, and the
builder built and indexed only those two architectures, so a riscv64
management node had no package to install. Both packages are now built for
riscv64, every release the repository serves declares the architecture,
and the generated mklocalrepo.sh maps a riscv64 host to its own repository
instead of amd64. Each package now carries its own architecture list:
xCAT-genesis-scripts keeps the two it has control files for, because
riscv64 Genesis ships as an OpenEmbedded package instead.

Drives the build with dpkg-deb and grub-mkimage shadowed by stubs, so the
assertions read the arguments that decide whether the image can boot over
the network: the firmware format, the prefix nodeset writes into, the
module directory, and the network modules. Also covers the warning a node
without a loader gets, an interrupted build leaving nothing behind, a real
riscv64 loader being kept, text, a truncated image, another architecture's
loader, images with nothing to execute and an image built for another boot
path all being replaced, and a rejected loader being gone when the media
cannot replace it.

riscv64 nodes have no boot loader unless one reaches /tftpboot/boot/grub2,
and nothing on an Ubuntu management node puts one there. The grub2 image
the media carry cannot serve: it holds a built-in configuration that looks
for the live filesystem, so a node that loads it drops to a grub prompt
instead of reading the configuration nodeset writes. copycd now builds a
netboot image from the grub2 package the media ship, and warns when it
cannot, because the node has no other source for one. An image already in
place is kept only when it is a whole executable image for the
architecture the firmware loads and carries the prefix this boot path
needs; one that is not is removed, so a rebuild that cannot run leaves
nodeset reporting a missing loader rather than serving an unusable one.
The media of every other architecture are untouched.

24.04 and 26.04 had no riscv64 package list, so a diskless image or an install
for the architecture fell back to the generic list and reached debootstrap
without a kernel or the tools the boot scripts call.
The lists hold the same packages as their x86_64 counterparts. Every one of
them is published for riscv64 in noble and resolute, main or universe.

The image carries the name service libraries of its architecture, and riscv64
matched neither the x86_64 nor the ppc64el branch. It fell through to the
generic path, which looks for lib/libnss_dns.so.2, so a riscv64 image shipped
without a resolver and the node could not resolve any name.
Ubuntu keeps them in lib/riscv64-linux-gnu, confirmed in the 24.04.4 riscv64
server filesystem.

The riscv64 live-server image keeps its kernel at casper/vmlinux, where every
other live image keeps casper/vmlinuz, so the probe found no kernel and mkinstall
reported that the install image was missing.
Add the riscv64 candidate pair and let copycd name the architecture the media
reports. Verified against Ubuntu-Server 24.04.4 riscv64, which carries
casper/vmlinux, casper/initrd and casper/install-sources.yaml.

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.
Both copies refused to run unless /usr/sbin/tcpdump existed. Debian and Ubuntu
install it as /usr/bin/tcpdump, so the rogue DHCP detector never ran there and
the probe reported its tcpdump check as failed.
Resolve tcpdump through PATH and the standard system directories with
CommandUtils::find_executable, run the resolved path, and match that path when
the capture process is killed at the end.
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 shared Ubuntu lists serve every release and architecture without a list
of its own, and ospkgs hands the whole list to one apt-get install, so one
unknown name loses every package on it. ntp and ntpdate are gone from 26.04.
libodbc1 is the unixODBC runtime name up to 22.04. libvirt-bin is gone from
20.04 on and qemu-kvm from 22.04 on.
The shared lists keep ntp and ntpdate, so releases up to 24.04 keep the
daemon they had. 26.04 gets release lists that carry chrony. unixodbc
replaces libodbc1 on every release, and the odbcsetup postscript keeps its
runtime. The service lists add libdbd-pg-perl beside libdbd-mysql-perl, as a
service node may run the xCAT database on PostgreSQL. libvirt-daemon-system
with libvirt-clients replaces libvirt-bin from 18.04 on; 12.04, 14.04 and
16.04 keep kvm lists with the old names.
qemu-kvm was a transitional name for the emulator of the host architecture,
and no current release has one name for that. Per-architecture kvm lists
name the native one: qemu-system-x86 on x86_64, qemu-system-ppc on ppc64el,
qemu-system-misc on 24.04 riscv64, with ppc64le linked to ppc64el as the
other lists do. The shared kvm lists fall back to
qemu-system, which carries every emulator, so an architecture without a list
of its own still gets one. On 26.04 riscv64 libvirt-daemon-system depends on
qemu-kvm or qemu-system and nothing provides qemu-kvm, so apt installs that
fallback there whatever the list names. Every kvm list names qemu-utils:
ospkgs installs without recommends, and libvirt needs qemu-img for the qcow2
volumes kvm.pm creates.
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.
The check ran on EL9 only, and only when the version carried a minor number,
so CentOS Stream was never checked. On EL10 a management node without EPEL
or CRB failed inside dnf install with a dependency error instead of the
message that names the missing repository. The CRB message proposed a CentOS
Stream repository file with signature checks disabled, on every
distribution. The probe used dnf list, which an installed copy of the probe
package satisfies with the repository disabled, and which reports a failed
query as a missing repository.
Check EL9 and EL10, with or without a minor version. Probe the enabled
repositories with repoquery for the host architecture and noarch, so a
source repository does not stand in for the binary one, and stop with the
package manager's own error when the query fails. Name the EPEL release
package of the running major version. For CRB, name crb enable from a
current epel-release, which handles Red Hat Enterprise Linux under both
subscription management and RHUI, Rocky Linux, AlmaLinux and CentOS Stream,
and the dnf config-manager command for Oracle Linux.
