Samba does not directly support ACLs on any OS.  That is to say, you
can't manipulate them from the client.  Sounds like this wouldn't be a
problem for you, as you would set it all up directly on the server.

I don't know much about ReiserFS -- at least not firsthand, since I
haven't tried it -- but SuSE ships and supports it.  Now, it is true
that Al Viro (kernel VFS guru) doesn't like the shape ReiserFS is in,
but (a) Al is very demanding, and (b) mostly what he doesn't like about
is is that it may well have boundary conditions ripe for security
holes.  Shouldn't be a problem if you don't give out shell accounts to
untrusted people -- we're not talking about *remote* exploits here.

I would give it a try.  Perhaps using SuSE, since they're the ones who
are actually shipping ReiserFS standard.
