The genesis image goes into a file whose name ends with .lzma. The plugin
writes that file only when /usr/bin/lzma is there, and it falls back to gzip
when it is not.
Red Hat ships no lzma binary. On AlmaLinux 9 and on AlmaLinux 10 that test
fails, the plugin falls back to gzip, and it gives no message that says why.
The image is larger on each run of mknb. Debian and Ubuntu ship lzma as a
second name for xz, so those systems still get the smaller image.
Ask xz for the same container when lzma is absent. The command
"xz --format=lzma" writes the same bytes as "lzma", so the file keeps its
name, its container and its size. Keep the gzip fallback for a system that
has neither program.
Recovered from the lenovobuild branch, which asked xz for the xz container.
That container is not the lzma container, and the name of the file says lzma.
Boot URLs handed to nodes always carried an explicit :80 even when the HTTP
server listens on the default port. grub2.pm already omits the port when it is
80; make the xNBA, genesis and DHCP boot URLs consistent with it.
$portsuffix is empty when site.httpport is unset or 80 and ":<port>" otherwise,
so a non-default port is unchanged. Covers the ISC and Kea paths in dhcp.pm,
xnba.pm, mknb.pm, and the Kea xNBA client classes in BootPolicy.pm.
dhcp_boot_policy.t and mknb_xcatd_address.t follow the new URLs and gain cases
for a non-default and an unset port. The floating-address guard in
mknb_xcatd_address.t also drops :80 so that it keeps matching.

b7db0e2, 792fe6d).

mknb writes the compressed genesis filesystem by streaming cpio output
straight onto the final path in $tftpdir/xcat (genesis.fs.$arch.lzma or .gz).
When two mknb/nodeset runs target a shared $tftpdir at once, one run reads or
overwrites the other's half-written image, producing a corrupt genesis.fs and
failed netboots.
Write each image to a uniquely-suffixed temporary file
(xCAT::Utils::genpassword(24)) and File::Copy::move() it into place. move()
within the same directory is a rename, so the final path only ever appears
complete. Both modules are already imported by mknb.pm.
Recovered from the unmerged lenovobuild branch (originals c651e7b8 and its
fix da0723f2, which switched the suffix to genpassword after the first
attempt only produced a single character). master lacks the branch's xz
path, so only the lzma and gzip paths are adjusted here.

The quiet kernel parameter was hardcoded in anaconda.pm and sles.pm,
making it impossible for admins to get verbose boot output without
editing plugin source code. The existing addkcmdline mechanism
(bootparams and linuximage tables) only appends to the kernel command
line, so there was no way to remove quiet.
Move quiet out of the plugin kcmdline construction and into the
linuximage.addkcmdline default set during copycds osimage creation.
Admins who want verbose boot for debugging can now remove it per
osimage:
chdef -t osimage <image> addkcmdline=""
New osimages get addkcmdline="quiet" by default. Existing osimages
with a custom addkcmdline are not overwritten on re-run of copycds.
Genesis/discovery boot (mknb.pm) is unchanged as it does not use
osimage definitions.
Addresses #6916
Previously the code which created the netboot config files was
incorrectly specifying the initrd file name in a number of places,
particularly in the xcat/xnba/nets/* files, using a hard-coded `.gz`
suffix even when a `.lzma` file had been created. This change ensures
that the initrd file name determined earlier in the code (either when
the image is created, or in the configonly case by checking the
filesystem) is used correctly when creating the netboot config files.
