	disklabel, installboot & ccdconfig also spring to mind :)

	On the other hand it would be _wonderful_ to have NetBSD/m68k
	with just the kernels (and maybe a handful of special files)
	unique for each architecture.... (IMHO :)

	The real win for this would be all the packages & userland
	programs would explictly be for NetBSD/m68k (I know they can
	be shared at the moment, but if 'uname' reported m68k as the
	architecture and everything was always referred to as 'm68k'
	then it makes things much nicer) (Apologies to the hp300 :)

	As long as the MD programs are unique between machines (ie
	no two machine have an 'iteconfig' which is different for eac
	machine), and the MD programs do not have any nasty side
	effects when run on the wrong machine (ie eeprom doesn't crash
	an amiga), then everything can be shared. (/dev is another
