What I'd like is for the list of `sets' (and their sizes,
descriptions, etc.) to be in a file that's either on the boot image or
accompanies the set files.  This would allow us to do a number of
things very easily -- have multiple X server sets on the i386, add a
local `athena' set at MIT, etc.

I'd also like to see some support for a sort of `express network
setup', in the same vain.  E.g., at MIT, I'd configure it like this:

subnet	  router     broadcast	    name servers
18.249/16 18.249.0.1 18.249.255.255 18.70.0.160,18.71.0.151
18.70/16  18.70.0.1  18.70.0.0      18.70.0.160,18.71.0.151
...

(Yes, 18.70 really does use all-0s for the broadcast address.  Don't
ask.)

Then the user should just type in the IP address, and the rest of the
network configuration would default to TRT if there was a matching
entry.

These changes would allow people to trivially create custom install
images for particular sites.
