If there's an MLS label change you're
in trouble.

You could argue that the administrative
facilities are composed of programs that
can be held responsible for policy
enforcement and that they can't do
anything wrong. This would be really
pushing the credibility envelope however,
and is an argument with a history of
failure. You might get away with it
if the new role's shell is restricted,
in fact, this is a situation where
SELinux could provide significant
leverage should you be able to describe
the environment provided in terms of
enforcement domains.
