Introduce owner-aware user namespace setup so containers get stable, per-container subordinate UID/GID ranges instead of ephemeral host mappings. Persist assigned ranges in container state, reuse them during start, and add managed subid cleanup through prune with coverage for allocation, lifecycle, and systemd drop-ins.

This makes sense to me. It also seems like this can enable a better provisioning for the ranges. Cheers! |
