comment Is there a reason why 'owner' permissions exist? Aren't group permissions enough?
You argue that what I described is an ACL, but this means that the current Linux permission scheme is a handicapped ACL, that's allowed to have only one user record, one group record and one record for Everyone (to use Windows lingo). I suggested modifying the handicapped-ness by rearranging the semantics. Rather than prescribing entities, prescribe permissions. This might be how traditional ACLs are implemented - I don't know. The point is, it comes as minimal cost, in terms of storage and simplicity, compared to the current state, still orthogonal, but with the full expressive power of ACLs.

comment fail2ban permission denied on script
Thanks for the comment. I found the solution, which had nothing to do with Python. Mind you, that I have the RHEL version of fail2ban, which uses os.system(). Adding a log message to print out the exact command used made me eventually get to the answer (see below). I would like to understand, though, how would you suggest that I enable debugging log level without changing code? I guess that's another question...

That might be. What I tried to emphasize is that currently each file record holds two IDs (group, owner) and a bitmask. Wouldn't it be more effective (again, the cost/gain argument) to just hold four IDs? (execute group, read group, write group, owner)

Bruce - you could ask the same question about find. But then there's locate.
