Correct me if I'm not interpreting this discussion properly, but aren't
we discussing reconstruction of the container (zpool/zfs-file-systems
and settings), not the data therein? Modes, ACL, extended attributes,
and ownership of the data, should all come over with a zfs receive, or
the backup recovery of your choice.
I believe I could write a trivial shell script to take the listings of:
# zpool list pool
and
# zfs list -r -t filesystem,volume -o all pool
to recreate the whole pool, and all the necessary properties.
