Builds the image on a self-hosted runner and publishes it, with the checksum and
a corresponding-source offer, as a Gitea release.
The schedule is daily but the build is conditional. Proxmox does not ship daily,
so an unconditional daily build would produce roughly 45 GB a month of
near-identical artifacts; instead the job compares the newest pve-manager in the
configured repository against the last published release and stops early when
they match. A manual trigger with `force` rebuilds anyway. Releases are tagged
after the version they contain (`pve-9.2.11`) rather than the date, so the tag
says something useful, and older ones are pruned to keep three.
The logic lives in scripts/ci/ rather than inline in the workflow. Shell inside a
YAML block scalar cannot carry an indented heredoc terminator, and the release
body needs several; scripts also mean the pieces can be run and tested by hand.
A `print-var` target exposes single Makefile variables to them.
Two constraints shaped this:
* The runner is registered in host mode, so steps run directly on the build
machine as root. The build needs /dev/kvm, qemu-nbd, FUSE and root, which a
container would have to be given anyway. The consequence — anything able to
dispatch a workflow gets root on that machine — is stated in the workflow
header rather than left implicit.
* Checkout is a plain git clone. actions/checkout is a JavaScript action and
the host-mode runner has no Node.js runtime.
The artifact is named maas-image-pve-<version>-amd64.tar.gz, not
proxmox-ve-*.tar.gz, and the release body says the build is unofficial and
unaffiliated. Proxmox permits redistribution under the AGPLv3 but asks that the
trademark not be used in product names.
SOURCES.md is generated per release: the image is an unmodified installation of
Debian and Proxmox packages, so it points at those archives for the
corresponding source, and records that the firmware licence texts ship inside the
image at /usr/share/doc/pve-firmware/licenses/ and must not be stripped.

The previous "Verified status" section listed the test environment and a
one-line result, which let readers assume far more coverage than the testing
justified. Options that had never run once were presented alongside ones that
were exercised repeatedly.
Every configuration option in the reference tables that was not exercised is now
marked "Untested" inline — 25 of them, including every PVE_NET_* value other than
the tested defaults, PVE_CLUSTER_LINK0/LINK1, fingerprint discovery, the join
retry path, and every PVE_THINPOOL_* value beyond auto with the defaults.
"Verified status" is now two lists. The first gives, per area, the observation
that supports the claim rather than the claim alone: which command was run, what
it printed, which file was found where. The second is everything that was never
exercised, with no implication that it is broken.
Three claims elsewhere were overstated and are corrected:
* the ~700 MB saving from a local APT cache is an estimate from package sizes;
that path has never been run
* MAAS 3.2+ is the documented minimum, but only 3.7.2 with snap packaging was
tested; the deb packaging's preseed path is untested
* the build timings are measured, but the contribution of each individual
optimisation is not
Both cases in "Moving to a new Proxmox release" are also marked: the minor-version
path is verified only as a mechanism (no package versions are pinned), never as an
actual version step, and the claim about upstream breaking on an unknown Debian
release is read from upstream's source rather than observed.
Verified while writing this: the iSCSI initiator names really do differ between
the two nodes, PVE_CLUSTER_WIPE_SECRETS really does scrub both password fields
after a join, and "make preseed" and "make install-preseed" work as targets on the
MAAS region controller rather than only as the commands they wrap.

Parts of this repository are derived from canonical/packer-maas, which Canonical
distributes under the AGPLv3, so its copyleft carries over and a permissive or
plain-GPL licence is not available:
* maas/curtin_userdata_custom.in is adapted from upstream's
debian/curtin_userdata_custom_amd64, with several late_commands copied
verbatim (the PXE-disable call, the target bind mount, the cloud.cfg rewrite
and the zz-update-grub fix)
* overlay/curtin/curtin-hooks follows upstream's debian/scripts/curtin-hooks:
same imports, same load_command_environment -> load_command_config ->
builtin_curthooks -> cleanup structure, near-identical cleanup(). The
kernel-disabling and interface-pinning functions are original.
The upstream template itself is not vendored; it is cloned at build time and
pinned by PM_REF.
Adds the full AGPL-3.0 text as LICENSE and SPDX-License-Identifier headers to
every source file, placed after the shebang or the #cloud-config marker so both
keep working. deploy-cluster.sh's --help filters the new header lines out of the
usage text it extracts from its own comment block.
GitHub Pages serves index.md, which includes README.md, so the site cannot drift
from the repository documentation. Nothing but build/ is excluded, which keeps
the README's relative links to LICENSE, scripts/ and maas/examples/ resolving on
the published site.

Builds a Proxmox VE image that MAAS can deploy to bare metal, plus first-boot
automation that configures the node and joins it to a Proxmox cluster with no
manual steps.
The image starts from the official Debian cloud image and installs proxmox-ve
on top of it, rather than capturing a raw disk from the Proxmox ISO. That keeps
MAAS in control of partitioning, networking, SSH keys and cloud-init, and makes
moving between Proxmox releases a variable change instead of a rewrite.
Contents:
* Makefile driving the whole flow: build, verify, preseed, upload
* customize-proxmox.sh, run inside the Packer build VM, which layers Proxmox
onto the Debian cloud image and resets the pmxcfs node identity so one image
can produce many nodes
* pve-maas-init, a first-boot state machine covering /etc/hosts, node-unique
identifiers, the root password, vmbr0 conversion, cluster create/join and
the local-lvm thin pool; each stage is resumable across reboots
* curtin-hooks, which stops curtin installing a kernel over APT and pins
interface names by MAC so they match what MAAS recorded at commissioning
* a MAAS curtin preseed template and cloud-init examples
* deploy-cluster.sh, which builds a whole cluster through the MAAS API
* verify-image.sh, 22 static checks on the produced tarball
Cluster identity lives entirely in deploy-time cloud-init user-data, so a single
image and preseed can build any number of independent clusters.
Verified end to end against MAAS 3.7.2: proxmox-ve 9.2.0 / pve-manager 9.2.11 /
kernel 7.0.14-15-pve, deployed to two machines that formed a quorate cluster with
local-lvm on both, with no manual intervention.
The README documents four failure modes found along the way that all fail
silently: curtin rejecting "kernel: null", pvenetcommit overwriting the network
configuration at boot, interface renaming leaving the link down, and a systemd
ordering cycle that made systemd delete the service's start job.
