Description: Access control list shared library
 This package contains the libacl.so dynamic library containing
 the POSIX 1003.1e draft standard 17 functions for manipulating
 access control lists.


ACLs are addons to *NIX. At least a couple of commercial *NIXen support them
( AIX, Solaris, HP/UX? ). Last I played with any they weren't compatable.

Using AFS on top of everything makes it all compatable, though. Presumably
the same for veritas filesystem stuff.

Seeing a reference for a POSIX standard gives me hope that we might someday
have a ubiquitous, standard ACL implementation. I wish we had it years ago.

Netware is based on System V to some extent, or so I'm told. In fact, rumor
has it that that's the reason Novell hasn't gone Open Source. Supposedly the
copyrights have finally run out ( or will soon ) and Novell wants to go Open
Source. They might even want to go Free Software.

I haven't heard anything beyond the initial rumor that was published in one
of their Novell news typeos of publications a couple of months ago.
