Btw, on Linux all the common filesystem support the SysV behaviour
by default but have a mount option bsdgroups/grpid that turns on the BSD
hebaviour.  I would recommend you do the same just with reversed signs
on FreeBSD.  ??Having different default behaviour for different
filesystems on a single OS is generally a bad idea.
