I believe ACLs are on by default in most distros now. At least in
Ubuntu. Just need to install the `acl` package. ACLs are stored in
extended attributes of the file system, so they will stay with the file
whether the mount option is used or not.

They are also compatible with standard POSIX permissions. They won't
hurt any programs.
