I've used a hacked-on version of Warner's scripts to build a FreeBSD
based firewall distribution to run on the Soekris 4501 box. I was
able to get a running system for that application on an 8MB CF card.
Of course, the kernel was compressed and it was pretty stripped down..
I'm currently using a 32MB CF card, with two 16MB partitions for this
purpose (so I can back up to the previous version easily).
Of course, no gcc. And heavens, no VI! Got a microemacs on there
instead, whew!
I also built my system with NOSHARED=no to dramatically reduce the
space requirements for the root (and only) file system, and it works
great.
