I would feel rather uncomfortable about having a su(1) in /rescue
that did not prompt for a root password, but rather just checked
for membership in the wheel group. It would in effect remove almost
the entire reason for having a root password to begin with, let
alone the effect on a properly Kerberised environment, etc.
If we do decide to put a su(1) in /rescue, we should try to ensure
that it provides a [not nec. proper] subset of the functionality
of /usr/bin/su and provides said functionality with the same code
as one finds in /usr/bin/su.
