acls have always been a portability sore point
we avoided doing anything because no-one has presented an api
that handles all our needs across varying architectures/implementations
in particular we need an api that
converts a string rep to binary
converts a binary rep to string
applies a binary acl to a file/fd
retrives a binary acl from a file/fd
I don't use acls because whenever they have been forced on me
I manage to get painted into all sorts of corners that prevent work at
inopportune times
a thing I really don't like is they bleed into non-acl apis/commands in strange
ways
should ls/chown/chmod/mv/ln grok acls?
what about other commands/apis that copy files and don't use cp(1) or pax(1)?
how much stuff needs to be added around each open(O_CREAT) to make acls
seamless?
is there an acl equivalent to umask(1)/umask(2)?
ast encompasses a lot of apis/commands
the main reason behind doing it in the first place is uniform semantics across
all of ast
I don't see uniformity in acls at the moment
but I can be convinced ...
