How about just including base & etc - that would still make them
generally useful without (hopefully) too much bloat.

A variation on the 'save space' option would be to build more of the
system as crunchgen - I believe Greg Woods had patches to allow
building a crunchgen full distribution bar PAM and something else.

And for token insanely overcomplicated option - build each of the
distrib files into a compressed vnd, and then union mount them all
readonly on top of each other in the CD startup scripts, and adjust
sysinst to be able to extract a distrib file from a compressed vnd.
(Please no :)

So... base & etc only, what does that sound like? :)
