I have to correct myself: it's not the ownership, it's (only) the  
group! Ownership is resolved by effectively using root to copy or  
move (otherwise it would fail due to permissions set). If copy is  
used, then the group owning the copy would be determined by the mood  
or mode root is working in right now, which can be other than wheel.  
If something is moved, then the original group membership can be  
preserved. So the set-group-ID-on-execution bit (2<plus the three  
well-known digits>) rectifies this group ownership. This bit can also  
be set by 'chmod g+t'.



Time is an illusion. Lunchtime, doubly so.
