True per user/group acl's as achieved via getfacl/setfacl

example:


caleb at chinstrap> touch foo
caleb at chinstrap> getfacl foo
# file: foo
# owner: caleb
# group: users
user::rw-
group::r--
other::r--

caleb at chinstrap> setfacl -m mysql:w foo
caleb at chinstrap> getfacl foo
# file: foo
# owner: caleb
# group: users
user::rw-
user:mysql:-w-
group::r--
mask::rw-
other::r--

caleb at chinstrap> tar cvpf test.tar foo
foo
caleb at chinstrap> rm foo
caleb at chinstrap> tar xpvf test.tar
foo
caleb at chinstrap> getfacl foo
# file: foo
# owner: caleb
# group: users
user::rw-
group::rw-
other::r--

Cheers,
