Changelog

1.0.0 - 2026-10-23

Breaking: state layout changed (private /etc, meta keys). Containers from 0.x must be deleted and recreated.

• Images: doos image list|add|delete, --image NAME on get_or_create/attach (fetched on demand). Catalog: alpine, ubuntu, ubuntu-VERSION; also https URL with --sha256, or a local tarball. sha256 verified before extraction.
• --size: cap for what a container writes (default 4g). Warns at 80%, freezes at 100% via cgroup v2, thaws below 95%.
• --ids: subuid mapping through newuidmap/newgidmap by default (chown, su and apt's _apt work); falls back to one id.
• Host mode fixes: directory skeleton so host-owned directories are writable, private copy of /etc, pre-seeded /var and dpkg state. apt-get install now completes.
• Deleting trees with subuid-owned files works (runs inside the id map).
• Usage measurement counts hard links once.
• Tests: 56 end-to-end checks, including real image downloads, apt/apk installs and the size freeze.
