no, not under my proposal.
Then your proposal is a non-starter. Support for
multiple remote
filesystem access protocols is key for ZFS and
Solaris.
The impedance mismatches between these various
protocols means that we
need to make some trade-offs. In this case I think
the business (as
well as the engineers involved) would assert that
being a good SMB
server is critical, and that being able to
authoritatively edit file
permissions via SMB clients is part of what it means
to be a good SMB
server.
Now, you could argue that we should being aclmode
back and let the user
choose which trade-offs to make. And you might
propose new values for
aclmode or enhancements to the groupmask setting of
aclmode.
but it sounds like currently people cannot ``fix''
permissions through
the quirky autotranslation anyway, certainly not to
the point where
neither unix nor windows users are confused:
windows users are always
confused, and unix users don't get to see all the
permissions.
Thus the current behavior is the same as the old
aclmode=discard
setting.
Now what?
set the unix perms to 777 as a sign to the unix
people to either (a)
leave it alone, or (b) learn to use 'chmod A...'.
This will actually
work: it's not a hand-waving hypothetical that just
doesn't play out.
That's not an option, not for a default behavior
anyways.

One question: Casper, where are you? The guy that did fine-grained
permissions IMO ought to have an idea of how to do something with ACLs
that's both safe and unsurprising for the various sorts of clients.
