explain how it could be more elaborate.  where do you put the mapping.
the auth server?

as far as i can tell, unless a kernel-generated file has permissions like 0064,
and the owner is eve, the group checking in the kernel doesn't do anything.

i should explain a bit the context.  since we have many folks with a use
for the aoe device on a few cpu servers, it would be useful to allow, say,
the fileserver group sys access to /dev/aoe/*.
