11 daysimage-builder: document the XDG_RUNTIME_DIR dockerd trapDanilo M.1-1/+13
A dockerd restarted from a root login shell inherits XDG_RUNTIME_DIR=/run/user/0. BuildKit's overlay differ creates its temp dir there, and once elogind removes it at logout every image export fails with a misleading "ref ... locked" error. This stalled the -current full image for three nights. The fix on the VM is `unset XDG_RUNTIME_DIR` in /etc/default/docker, which rc.docker sources.

Also records the host config the chain depends on. The schedule and the storage layout existed only on the VM, so a rebuilt host would have lost both, and the README's inline copy of the schedule had already drifted from what actually runs. crontab.example is byte-identical to the deployed crontab; fstab.example carries the two-disk layout and the dockerd mount-namespace trap that makes moving the registry store non-obvious.

2026-09-10image-builder: add safe registry GC and stop OCI-index breakageDanilo M.1-3/+52
The registry never reclaims blobs, so its store grows until the disk fills and the nightly builds fail with "no space left on device". Add registry-gc.sh, run weekly (Sunday 08:00), plus a daily dangling-image prune. registry-gc.sh refuses to run while a build is active, stops the registry for a stable blob graph, deletes only untagged manifests (-m) and their blobs, restarts via an EXIT trap, and verifies a tag still pulls. distribution 2.8.x GC does not follow OCI image indexes, so -m deletes their child manifests (distribution#3178). Default BuildKit provenance made every pushed tag an OCI index, which made -m destructive. Build scripts now pass --provenance=false (plain schema2), and registry-gc.sh refuses to run if any tag is still an index.
2026-07-14initial commit: docker test-build toolchainDanilo M.1-0/+69
Extracted from the .extras/ dir of the sbo-slackbuilds package repo, where it grew from a throwaway helper into a standalone tool. Git history starts fresh; the original 41-commit development log is preserved in HISTORY.md. Contents: the test-build CLI (resolves a local SlackBuild's deps from a configured SBo tree and builds it in a throwaway container, lints, caches deps), the image-builder chain that produces the images it consumes, their pure-logic self-checks, design specs/plans, an install.sh for ~/bin, and docs.
