 Expecting the primary group listed on my id. I guess I never realized 
 that it used the parents group. I expected it to give the id/group that 
 I belong to.
 The basis of the reason for my interest is that I'm trying to use 
 NAS4Free, and when I create a volume and export it out NFS, every file 
 is getting the wheel group there too. I'm expecting it to pick up the 
 group of the user like our NetApp does. I tested on Linux, and when I do 
 the same things in /foo it creates it with my id/group, not the one 
 above. If I was to just use a normal FreeBSD NFS setup, how can I make 
 it pick up the user/group of the person creating the file (We are using 
 it exported to a farm of CentOS...We wanted FreeBSD due to ZFS).
