I don't see the point in allowing the acl's to refer to arbitrary
user at domain strings unless we're also going to allow those strings as
file owners, allow processes to run *as* one of those strings, etc.

If we're really going to try to teach the core kernel to handle foreign
NFS or Samba identities, that's a separate project.

As long as the kernel's working with ordinary uid's and gid's, the acl's
should do the same, and NFS and Samba can take care of the conversion as

So I agree that we should be able to use a more compact representation
