Subject Re: [VFS] setting read-only, hidden, etc

It could be mapped, but would have a lot of additional constraints. For 
example with an ACL, you can generally assign any permission to any user 
or group. With Unix-like - you only get one definable group, one fixed 
group (other), and one user. So I guess mapping it would be easy, but I 
would think in that case we would want to have discoverable capabilities 
for determining if more than one user, group etc can be added so that 
programmatically such things are predictable.
