Replying to the first post in the thread.

One first thing to help people to avoid problems with future upgrades
could be to just make / 1G:
http://people.freebsd.org/~bz/20100124-03-sysinstall-root-1g.diff

Another entirely untested patch would compress the symbol files:
http://people.freebsd.org/~bz/20100124-04-kernel-compress-symbols.diff

It would be interesting to see if (a) they work and (b) how much the
latter would safe.
