zfs discuss - Apr 2011 - aclmode -> no zfs in heterogeneous networks anymore?

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA256

Hi!

We are setting up a new file server on an OpenIndiana box (oi_148). The
spool is run-in version 28, so the "aclmode" option is gone. The
server
has to serve files to Linux, OSX and windows. Because of the missing
aclmode option, we are getting nuts with the file permissions.

I read a whole lot about the problem and the pros and cons of the
decision of dropping that option in zfs, but I absolutely read nothing
about a solution or work around.

The problem is, that gnome''s nautilus as well as OSX'' finder
perform a
chmod after writing a file over ifs, causing all ACLs to vanish.

If there is no solution, zfs seems to be dead. How do you solve this
problem?

Using Netatalk for giving Macs native AFP support. Latest Netatalk has
a workaround (basically a chmod(3) wrapper) builtin.

Best!
