OK, then is it possible to use this feature to span vservers from the main
server. Currently I'm resetting the UID/GID MIX/MAX in each vserver so
they can be unique across all vservers. I use the context (assigned per
vserver) as the - upto - first three numerals ie., UID_MIN 3100, UID_MAX
3199. Gives me a clue when I'm really tired which vserver's disk space
I'm looking at from the main server. I'm hoping to discover a way to
blend/mix all the passwd files so I get user ID 'xyzzy' when listing files
for the 'xyzzy' vserver's main user - xyzzy.
Maybe I'm chasing rainbows with this idea.
