On 3.4 (and the same is in 4.x i think) i removed the forth stuff from
the loader, and then you don't need all the config files, just a 3-4
line thing (same as Greg did) to load kernel mfsroot and then boot.
So i have
> ls -l /boot/loader
-r-xr-xr-x 1 root wheel 131072 Dec 30 1999 /boot/loader
> (cd /usr/src/release/picobsd/build; ls -l /loader )
-rwxr-xr-x 1 root luigi 53754 Jun 14 17:37 loader
(with the second one being used in the picobsd disk).
Assuming the 20% bloat in 4.0 there you are with 70KB (and i
suppose some of the size increase in 4.x is due to more
functionalities put into the forth stuff).
cheers
