Uh.  Ofcourse I meant 'code'.  I have no idea how the word
'login' got there...

Dale proposed that each init script checks itself whether it
needs to be started, from some central location.  I think this
is not good, it takes away flexibility.  IMHO it would be better
if only /etc/init.d/rc (& rcS) checks whether a service should be
auto-started on boot.  That way the responsibility is also
divided better, init-script's business is to start a service
and rc/rcS business is start boot-time services.

One easy hack woud be to replace '-f' with '-x' in following
code in rc, rcS:

	[ ! -f "$i" ] && continue

then later you can 'chmod -x' init scripts.  Problem with
this is that on upgrade your 'settings' will be lost.

Better would be to put the chkconfig into those loops.
