Well, as the original poster, my thoughts were fundamentally to speed
along the 1.0VUP and down boxes, typified by my usual sort of slow MVII
critter.  Pulling some bits out of /etc/netstart, and reducing the
ifconfiggy pudding down to a one-liner ``ifconfig qe0 inet mv2'' kind
of thing sped up the booting by maybe 15 seconds or so.  For the sake
of disussing and resolving some minimalist issues on things like the
MVII critters, how far can things be minimized, or could a single-pass
mini script be alternated out of the top of the big 1.5 rc suite, so
as to keep things trim on the lesser machines?  If something like
that were done, then if the boot sensed a slow machine like an MVII,
the operator could set a flag in the original rc callup that would
trigger using the mini scripts.  On biggie boxes, then, the full
script set could be used.

More thinking out loud.....
