zfsutils-linux normally enables zfs-import-cache/zfs-mount/zfs-zed/
zfs.target in its postinst, but a broken or interrupted install (or a
minimal image) can leave them disabled. Without them a reboot leaves
the ZFS module unloaded and the pool unimported, so Incus's storage
pool is gone and every container fails to start.
00-check.sh now explicitly enables the boot units after verifying the
module loads. Verified with a real host reboot: module auto-loads, the
vpsmgr pool imports ONLINE, and Incus + the panel come up on top.
