While we are on this topic, wouldn't it make sense to introduce unique
identifiers, which can be associated with users, groups, or any other
kernel object for that matter, then this is the entity you charge. The
kernel can then map the id to the user or group (or whatever object).
When ACLs are introduced they would grant/deny permissions and in general
operate only on unique identifiers.
This would have the benefit that the identifiers can be made sufficiently
unique to work on a whole network (or even larger scales), which would make
user management much easier for large corporations, much akin to what
Netware and Windows servers do in fact...
Just my 2p.
