Even better is that NFSv4 (allegedly coming in 2.6) will support them as
well! (as does my Network Appliance fileserver)
We have near-constant group permission issues due to users with mis-set
umasks, tar ignoring the group directory sticky bit, and other such
complications. I -almost- switched our central filesystem to CIFS
security a couple of times for the ability to say "this directory and
everything under it is writeable by this group, and readable by these
other two groups".
It's a very very very good thing.
