We need _some_ backup format that will preserve ZFS ACLs. star doesn't
(yet), nor does any other version of tar that I know of. Sun's cpio
didn't use to (I haven't tested it recently, anyone know for sure?), and
if it does now, it's still cpio *shudder*. Even rsync doesn't support
ZFS ACLs (yet).
It would be _really_ nice if someone familiar with the rather badly
documented ZFS ACL APIs would contribute code to give us some working
options. I suspect star and rsync are the least work, as they already
have ACL frameworks. And if Sun's cpio doesn't have ZFS ACL support yet,
that really needs to happen.
I actually took a look at doing this for rsync, but I didn't have enough
time to learn the API by trial-and-error.
