Fix five real bugs found by actually installing and running the plugin
First live end-to-end install on real Unraid hardware (all 8 built
packages installed via upgradepkg, rc.podman started, containers
pulled/run/networked/port-mapped) — surfaced five genuine bugs no
amount of container-based CI testing could have caught, since none of
them exist inside the vbatts/slackware:15.0 build container:
1. rc.podman never created $PODMAN_LOG_DIR before redirecting the
podman system service's output into it, so the service failed to
even start ("No such file or directory"). Added it alongside the
existing PODMAN_RUN_DIR mkdir.
2. config/storage.conf hardcoded a [storage] table, and
podman-config.sh's `sync` step appended a second one at boot with
the real graphroot/runroot — TOML forbids defining the same table
twice. Removed the template's [storage] entirely; sync already
generates the whole thing.
3. config/policy.json had a "_comment" pseudo-field for
documentation, but containers/image's policy parser rejects any
unknown top-level key outright. JSON has no comment syntax; moved
the rationale into docs/ARCHITECTURE.md instead.
4. netavark >= 2.0 dropped its iptables firewall driver entirely
(verified: passing "iptables" is flatly rejected) — nftables or
firewalld are the only remaining options, and firewalld needs
systemd/dbus, which Unraid has neither of. Set firewall_driver =
"nftables" explicitly and documented that Unraid OS doesn't ship
the `nft` binary this needs (a slackware64 nftables package works;
not yet wired into the build/install pipeline — see follow-up).
5. Every container failed with "crun: pivot_root: Invalid argument".
Root cause: Unraid's / is permanently the kernel's initial "rootfs"
pseudo-filesystem (Unraid never pivots to a real one at boot — the
whole OS runs from RAM), and pivot_root(2) unconditionally rejects
that as the old root. This is not new: Docker/runc hits the exact
same kernel restriction on this exact host and silently falls back
to an MS_MOVE-based chroot; crun has no such fallback, only a
--no-pivot flag with no config-file equivalent. Added
plugin/sbin/crun-no-pivot.sh, a thin wrapper that scans crun's full
argument list (podman puts global flags before the subcommand, so
the subcommand isn't reliably $1) and injects --no-pivot right
after create/run, and pointed containers.conf's crun runtime at it.
Also fixed the podman.plg postinstall's chmod glob
(`podman-*.sh` -> `*.sh`), which would have skipped this new
non-podman-prefixed sbin script.
Verified end-to-end on the real host: pull, run, real network
connectivity (wget through the container's bridge), and a published
port actually serving HTTP (curl through -p 8099:80 to nginx) all
work. --no-pivot's security tradeoff (disabling one particular
container-escape mitigation) was explicitly discussed with and
approved by the user before committing, given it must be the default
for any container to start at all on this platform.
Follow-up not yet done: nftables (needed for #4) is not yet a
packages/ component in the reproducible build pipeline — it was only
installed manually on the test host for this verification run.

Add reproducible build system, native Unraid plugin, and WebUI
- versions.env pins podman, conmon, crun, netavark, aardvark-dns, passt, and fuse-overlayfs to verified upstream source checksums; SlackBuild recipes, scripts/build-packages.sh, checksums.sh, release.sh, and update-versions.sh implement the reproducible pipeline; GitHub Actions workflows build in a Slackware container and publish releases without committing any binaries. - plugin/podman.plg installs/updates/removes all eight packages (the seven components plus the plugin's own unraid-podman scaffolding package) via upgradepkg, using the official Unraid array-event hook mechanism (event/disks_mounted, event/stopping) instead of editing /boot/config/go. rc.podman and the sbin/ helper scripts implement storage creation, config seeding/sync, preflight checks, autostart with per-container Safe-Mode, and package verify/update/rollback. - webui/plugins/podman implements the Dashboard, Containers, Pods, Images, Volumes, Networks, Logs, Terminal, Compose, and Settings panels against the approved mockup (webui/mockups/prototype.html), talking to podman system service exclusively via PodmanClient.php (libpod REST API over the Unix socket), with two documented exceptions: Terminal's one-shot exec model and Compose's use of the podman compose CLI, since libpod has no REST equivalent for either. - docs/ARCHITECTURE.md and docs/ROADMAP.md record the design decisions and honest current status (syntax-checked, unit- and integration-tested against fake sockets/servers; not yet run against a real Unraid/Podman/Slackware system).
