Zfs nogrpid | sysvgroups option?

[Boyko Yordanov]

Hello!

Running latest FreeBSD 11.0-RELEASE-p1, zfs as root filesystem, there doesn't seem to be a way to switch from bsd-groups to sysv-groups style for group ownership. Directories behave as if they have the setgid flag set (chmod g+s or chmod 2770) while they don't. Actually, the setgid flag is not taken in account at all - all newly created files inherit their group from the directory they reside in.

I’m looking for a way to change this so that newly created files get the primary group of the user who created them (sysv behavior - default on Linux). I checked the zfs dataset properties, mount options, kernel options, fs acls and chmod flags and couldn't find a way to achieve this.

Am I missing something?
