We use a switch on $sysname:

	switch($sysname){
	case thresher
		...

	case achille
		...

	}

etc.  An alternative is to use

	if(test -x /sys/lib/sysconfig/cpurc/$sysname)
		/sys/lib/sysconfig/cpurc/$sysname

which scales a bit better, makes it easier to let different
people administer different systems, but splits the config
info into multiple places making it harder to read.

To answer your specific questions, you'd probably want
to start the auth services only in the case for your auth
server; we let all the cpu servers share the same ssh
host key.
