Phase 6 of v0.3. The update agent now refuses to apply artifacts whose
channel doesn't match local policy, whose architecture differs from the
running host, or whose min_compatible_version is above the current
version. It also refuses to apply outside a configured maintenance window
unless --force is given.
New package update/pkg/config:
- config.Load parses /etc/kubesolo/update.conf (key=value, # comments,
unknown keys ignored). Missing file is fine — fresh systems before
cloud-init has run.
- ParseWindow handles "HH:MM-HH:MM" plus the wrapping midnight case
(e.g. "23:00-01:00"). Empty input -> AlwaysOpen (no constraint).
Degenerate zero-length windows never match.
- CompareVersions does a simple 3-component semver compare with the 'v'
prefix optional and pre-release suffix ignored.
- 14 unit tests total.
update/pkg/image/image.UpdateMetadata gains three optional fields:
- channel ("stable", "beta", ...)
- min_compatible_version (refuse upgrade if current < this)
- architecture ("amd64", "arm64", ...)
update/cmd/opts.go reads update.conf and merges it into opts; explicit
--server / --channel / --pubkey / --maintenance-window CLI flags override
the file. New --force, --conf, --channel, --maintenance-window flags.
Precedence: CLI > config file > package defaults.
update/cmd/apply.go gains four gates in order:
1. Maintenance window — checked locally before any HTTP work; skipped
with --force.
2. Channel — refused if metadata.channel doesn't match opts.Channel.
3. Architecture — refused if metadata.architecture != runtime.GOARCH.
4. Min compatible version — refused if FromVersion < min_compatible.
All gate failures transition state to Failed with a clear LastError.
cloud-init gains a top-level updates: block (Server, Channel,
MaintenanceWindow, PubKey). cloud-init.ApplyUpdates writes
/etc/kubesolo/update.conf from those fields on first boot. Empty block
leaves any existing file alone (so hand-edited update.conf survives a
reboot without cloud-init re-applying). 4 new tests cover empty / all /
partial / parent-dir-creation cases. full-config.yaml example updated.

Phase 4 of v0.3 — KubeSolo version bump and CI gating.
KubeSolo v1.1.0 → v1.1.5 brings:
- New flag --disable-ipv6 (v1.1.5)
- New flag --db-wal-repair (v1.1.5) — important for power-loss resilience
on edge appliances; surfaced as kubesolo.db-wal-repair in cloud-init
- New flag --full (v1.1.4) — disables edge-optimised k8s overrides
- Pod egress connectivity fix after reboot (v1.1.4)
- Registry config persistence fix (v1.1.5)
- k8s 1.34.7, CoreDNS 1.14.3, Go 1.26.2
All three new flags wired into cloud-init: config.go fields, kubesolo.go
extra-flag emission, full-config.yaml example.
Supply-chain hygiene:
- Per-arch checksums: KUBESOLO_SHA256_AMD64 and KUBESOLO_SHA256_ARM64 in
versions.env. Replaces the single shared KUBESOLO_SHA256 that couldn't
meaningfully verify both binaries at once.
- Checksum now applied to the tarball (the immutable upstream artifact)
rather than the post-extract binary.
CI:
- New .gitea/workflows/build-arm64.yaml routes the full kernel + rootfs +
disk-image build to the Odroid arm64-linux runner. Triggers on push to
main, tags, and manual workflow_dispatch. The boot smoke test is
continue-on-error because KubeSolo's first-boot image import deadline
fires under QEMU TCG on the Odroid.
VERSION bumped to 0.3.0-dev. CHANGELOG entry under [0.3.0-dev] captures all
Phase 1-4 work + the known limitations documented in arm64-status.md.

Add missing flags (--local-storage-shared-path, --debug, --pprof-server,
--portainer-edge-id, --portainer-edge-key, --portainer-edge-async) so all
10 documented KubeSolo parameters can be configured via cloud-init YAML.
