Well, for one thing, this is not kernel related. All the kernel does
is keep track of which processes have which gids and supplementary
group ids. login parses /etc/passwd and /etc/group to determine
what the uid and gids the process it spawns should have. It is fairly
easy to set up a system whereby /etc/group is automatically generated
from a database where certain groups are user-modifiable.
