With all due respect Joerg, that's nice but not very useful :-)  The kernel
alone will take 2/3 the floppy.

I don't know of anywhere that documents it, unless you count the stuff
in /usr/src/release.

I did, at one point, take what's there and create a "router floppy" from it,
using a compressed kernel and a built-in kernel MFS, the same way that
boot.flp does.

It was actually kinda slick...  you can take arbitrary programs and stuff
and create a single "crunched" binary from them (see man -k crunch).  You
then populate your /bin or /stand with that binary and a bunch of hard
links...  make your /dev and /etc trees and anything else you need... and
go off on your merry way.

I make it sound so easy.  :-)  It was a six hour hack job to make it
buildable from a makefile.... not too hard just a little slow to do the
"make"/"make floppy"/boot it/find problem/ etc cycle...
