The API doesn't favour any one form of ACL - it allows for any
implementation to be layered above it, provided the semantics
of those ACLs can be expressed using extended attributes, of

Yes, I believe so. I see EA and ACL support is on the JFS todo
list - I was contacted by some folk at IBM who let me know this,
so there is certainly some interest there.
