This brings up an interesting, but probably quite complicated question: is it
reasonable to try to express Windows permissions using full POSIX ACLs (not
the traditional UNIX mode, the full-featured complex beast that most users
know nothing about and that many file systems don't enable by default) -- or
is it, maybe, possible to express the Windows permissions model as a subset of
I'm no expert either, but the basic idea is that you replace the traditional
UNIX model with one where not only does every file have an owner and an owning
group, and r/w/x permission bits for owner, group, and "the rest", but you can
also specify permissions for arbitrary users and groups, in addition to the
standard set. I'm leaving out all the details, of course, first and foremost
those I don't know about myself, but that's essentially it.
Do Windows NT permissions do anything more? Or, apart from the "executable"
bit, anything less, for that matter?
Just asking. Maybe there are some experts around.
