My impression is that there are "POSIX ACLs" which are compliant with a
withdrawn draft, and there are "NFSv4 ACLs" which have a spec and are a
superset. And then that Linux implements the semantics of POSIX ACLs
(fine), stores them in os-specific EAs (ok) but either does not
implement the withdrawn-standard interface or nobody on linux uses it
I think this might be a package that provides the POSIX interfaces, so
that programs written to POSIX will work on Linux. That implies that
GNU/Linux systems tend to have a non-standard ACL interface,
If that's true, then this is
Implement POSIX ACLs using Linux's not-really-POSIX ACL implementation
and it can be ONLY_FOR.
If it is trying to do something that isn't "implement the standard
interface", then it's a good question why it isn't BROKEN_ON instead.
Howver, all my attempts to understand this so far have felt like "You
are standing at a crevice. You are holding a document that specifies
POSIX ACLs, which weighs several pounds. There is a POSIX language
lawyer standing in a shadow nearby, looking menacing, and to the north
is a maze of twisty passages, all alike."
