This needs a little work to fix in -current, and back to -stable.

Recently the /boot/loader was removed from the PICOBSD build to free up
space on the floppy image.  This meant that we had to put the MFS
filesystem back into the kernel, rather than use the loader to pull the
image off the disk.

The kernel needs an 'options MD_ROOT_SIZE X" adding to its 
config file before it builds, and the full mechansim to organise this
hasn't been build into the ./build process yet.

(We're working on it - patches welcome :O)

Which picobsd build are you making?  Have a look in the PICOBSD file
in its directory and add an option, as above, if it's not there. The X
stands for the memory file system size, and should be the same as you
use in the ./build config screen.
