From my point of view it works the same way as on UFS. Emil- Thanks for your response... I don't know that that's quite right. SUIDDIR has to be enabled in the kernel as an option to enable the functionality on UFS and my tests on ZFS haven't proved fruitful: $ sudo zfs create zroot/shared $ sudo zfs umount zroot/shared $ sudo zfs mount -o suiddir zroot/shared $ sudo chown sats:office /zroot/shared $ sudo chmod 4770 /zroot/shared $ touch /zroot/shared/file $ ls -al /zroot/shared/ total 4 drwsrwx--- 2 sats office 3 Dec 16 23:26 ./ drwxr-xr-x 4 root wheel 9 Dec 16 23:26 ../ -rw-r--r-- 1 ben office 0 Dec 16 23:26 file With a drive mounted with the 'suiddir' option (and the kernel option enabled) the above works with UFS. I was curious if maybe there was an option in 'zfs set' that I was missing. Any clues would be appreciated. Ben
