I don't understand POSIX ACLs, but I didn't say there was an ACL for FRED@FOO, I
just said there was a mode (700). Does this mean on POSIX that it automatically
creates an ACL for user FRED???? On non-POSIX systems, were ACLs not separate
entities and doing a "CHMOD 700 l.l" just set the mode in the inode and did
nothing to the ACLs. Adding an ACL for a specific user, did it also create ACEs
for the "OWNER", "GROUP", "OTHER"???

Good question.
