The order of the groups matters if the list has to be truncated for any
reason - when you want a choice over the groups that get discarded.
When I had time, I considered removing the kernel limit on the number
of groups. This would lead to the NFS code having to truncate the list.
I still have:
$ grep u2100 /etc/group | wc -l
