The step that fills lib/firmware in the Ubuntu netboot initrd asked modinfo
about $rootimg_dir/$module and looked a firmware name up under lib/firmware.
The copy step beside it takes a module from $customdir or $pathtofiles first,
and the kernel looks a firmware name up under updates/<kernel>, updates/,
<kernel>/ and lib/firmware. So a custom driver reached the initrd with no
firmware, even when the root image carried it, and a firmware override was left
out of the initrd altogether.
initrd_firmware_files now takes the module directories the copy step searches
and the kernel release. It resolves each module in that order before asking
modinfo, and keeps every firmware file that exists in the four directories the
kernel searches, so the override still wins on the node.
ubuntu_genimage_initrd_firmware.t covers both: its two new cases are red on the
commit before this one.

The ubuntu-26.04-ppc64el diskless node never starts its kernel. SLOF reports
W3411 and E3406 and falls through to disk. The node fetches the kernel and the
initrd in under a minute and fails six minutes later, with no network activity in
between: grub2 has the payload and cannot start it.
genimage copies the whole lib/firmware tree of the root image into the initrd.
That tree is 666 MB on Ubuntu 26.04, which takes the initrd to 719 MB. A 687 MB
initrd boots the same kernel on the same node; a 719 MB one does not.
The firmware copy now takes only the firmware that the drivers in the initrd ask
for, which modinfo reports for each module. The root image keeps its whole tree,
so the node that boots is unchanged.
ubuntu_genimage_initrd_firmware.t drives the firmware step over a root image whose
firmware tree holds files no driver asks for. It fails on the previous commit.

Both copies wrote the capture to /tmp/dhcpdumpfile.log, so a file left by
another user or an earlier root run blocked the probe and two runs
overwrote each other. tcpdump ran behind a shell, so the script killed it
by searching the process table for any tcpdump on the interface, and a
tcpdump that failed to start left an empty file that read as zero DHCP
servers. An interrupt left the capture running.
The capture file is now a private temporary file removed on every exit.
The child execs tcpdump itself, so the script stops and reaps exactly that
pid, and a tcpdump that ended before the window did fails the run. A
failed send and an INT or TERM stop the capture and exit 1 as well.

xcat-server ships xcatws.cgi and restapi.pl with the endpoint enabled in
apache, and both load CGI at top level. Nothing declared the module, so on
a management node where nothing else pulled it every /xcatws request
answered 500. The rpm package requires perl(CGI).

mkinstall mapped x86_64 and x86 to their Debian names and accepted ppc64le
and ppc64el. Every other architecture, riscv64 included, was logged as
"Unknown arch" on each diskful install, although the install went on with
the name unchanged, which is right for riscv64.
Move the mapping into install_darch, which takes the Debian name from
xCAT::Utils::debian_arch and knows the architectures xCAT installs Ubuntu
on. riscv64 is one of them.

copycd builds the riscv64 boot loader by running grub-mkimage, which
grub-common ships on every supported Ubuntu release. Nothing declared it, so a
management or service node installed without that package copies riscv64 media
and produces no loader, while DHCP keeps pointing every riscv64 node at the path
where the loader should be.
The declaration belongs to xcat-server, which carries the plugin that runs the
command, so both metapackages inherit it.

The note shown when boot/grub2/grub2.<arch> is missing told the

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.

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.

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.

archive.ubuntu.com publishes amd64 and i386 only, so debootstrap could not

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 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 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 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.
getcredentials answered xcat_secure_pw only for root, so a postscript
had no way to get the password of another node account from the passwd
table.
xcat_secure_pw:<user> now returns the password field of the passwd row
key=system,username=<user> when <user> is root or a sudoer named in the
postscripts or postbootscripts of the requesting node, its osimage, or
xcatdefaults. A sudoer without a row or without a password gets the
locked field "!", so the node applies the reply as is. Any other user,
an invalid user name, or a failed hash answers with an error instead of
an empty reply. The root request reads the same row as before and keeps
the error reply for a missing row.
genimage translated one architecture for debootstrap, x86_64 to amd64, and
compared against a bareword rather than a string, which only resolves because
the script does not enable strict subs.
Read the name from xCAT::Utils, which genimage already loads. Every
architecture reaches debootstrap with the name it does today.
copycd translated the architecture the Ubuntu media reports with its own
if/elsif chain, and genimage translates the same names back for debootstrap with
another one. Neither can be reused, so a new architecture has to be added to
both.
Put both directions in xCAT::Utils and have copycd read from there. The names
and the fallback do not change: media that xCAT has no name for still leave the
architecture as the media reported it.
The probe spelled out every candidate path twice inside one nested condition,
once to test it and once to assign it, so adding an architecture meant adding
another branch of the same shape. Move the candidates into a table keyed by
architecture family and walk it in order.
Same paths, same precedence, same failure behaviour: a media tree that matches
nothing leaves the caller on the "install image not found" path as before.
The boot flip in compute.subiquity.tmpl addressed 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 back into the installer. The flip now reads
site.xcatiport and keeps 3002 as the default. TABLEBLANKOKAY, because the key is
optional and a plain TABLE lookup of an absent key fails the whole template.
The flip also counted any reply as an accepted request. It now requires the
monitor's "ready" greeting before it sends "next", and "done" afterwards, so a
different service on that port is not read as a flipped node.
subiquity_nfsroot_server in debian.pm called getipaddr without a family. A
dual-stack management node answers with its IPv6 address, and casper takes
everything after the first colon in nfsroot= as the path, so the live filesystem
never mounts. It now asks for IPv4, as dhcp.pm and mknb.pm do.
The DNS setup wrote the xcatmaster name as a nameserver when getent found no
address, which is the case the step exists to prevent. It now keeps the
resolv.conf DHCP gave the live installer.
ubuntu_subiquity_boot_flip.t, debian_subiquity_boot_params.t and
ubuntu_resolvconf_ip.t fail on the parent commit and pass here.

`makedhcp -q <node>` on Ubuntu's ISC-limited releases answers "no DHCP reservation
found" when it cannot read dhcpd.conf. The operator reads that as a node without a
reservation. An InfiniBand node also gets an answer with no hardware address.
_query_isc_static_host in dhcp.pm read the file with an -r test and dropped a failed
open. It also matched only a "hardware ethernet" line, while _add_isc_static_host
writes "hardware infiniband" for an InfiniBand node and adds a twin declaration
between the same markers.
_read_isc_conf_lines now returns the read error, _query_isc_static_host returns it to
listnode, and listnode answers the caller with an error. The parser accepts any
hardware type and keeps the first declaration of the block. The path of dhcpd.conf and
the distribution name are package variables, so a test can drive the query and
listnode.
dhcp_isc_static_host_query.t covers the InfiniBand address, the twin declaration, the
unreadable file and the listnode answer. It fails without this change.
