Hi,

can someone point me to what has changed in file creation modes in
/tmp directory?

# FreeBSD 6, 7:
$ cd /tmp; id; touch testfile; mkdir testdir; ls -la
uid=65534(nobody) gid=65534(nobody) groups=65534(nobody)
drwxr-xr-x   2 nobody  wheel   2 Sep 16 22:10 testdir
-rw-r--r--   1 nobody  wheel   0 Sep 16 22:10 testfile


# FreeBSD 8:
$ cd /tmp; id; touch test; ls -la test
uid=65534(nobody) gid=65534(nobody) groups=65534(nobody)
drwxr-xr-x   2 nobody  nobody   2 Sep 16 22:12 testdir

On FreeBSD 6,7 files are created with wheel group, but on 8 - with `gid`.

It seems that ZFS uses SysV group semantics (new files get the 1ary group of

directory unless the user is not a member of that group, when they get the
users' 1ary group).

There's a thread 'ZFS Group ownership'  on this topic in freebsd-hack...@...
at the moment.

        Cheers,

        Matthew
