Actually, ACLs are not entirely loony. The ability to add a per-group
access is all well and good, but the hoops you have to go through to
say that "I want everyone EXCEPT this user to be able to access this file"
are hairy. You can't just take him out of the group, necessarily,
and for obvious reasons you can't just chown the file to him (although
chflags makes this a bit easier, now that I think about it).

I won't argue with that one, but outside of the massive disorganisation
of Linux' userland, the majority of its weaknesses are in the kernel.

Given chown/chgrp, chmod and chflags, I don't really care either way
as long as ACLs are, as always, _an option that I can disable_.

Hard to say this, but if the feature makes sense AND we can do it in
a non-performance-impactive manner (i.e. the gain far outstrips the bloat),
then why not?
[Please note: I'm not turning coat, here, but some features do make sense.
Just let me disable the ones I don't use, if I want to unbloat my system.]
