won't know until Poul wakes up again).
2. Make vsystem() put its output on the debugging fd.
3. DTRT with root filesystem placement - now I see how this has to work
(thanks, Poul).
4. Many miscellaneous spelling errors fixed and general cleanup.
It remains to be seen how successfully. The distribution loading code
is still not here yet, but the partition/newfs/mount/cpio-extract cycle
is as complete as it's ever going to get, modulo possible bug fixes.
The TCP/IP setup screen is also sort of here, albeit in a highly-changing
state due to the fact that per-interface information isn't being kept
right now but is being added (thanks, Gary!).
Do another clean-up pass over this, making the generic menu handler much
more powerful (now handles multiple dispatch). A few more menus fleshed
out and the beginnings of the distribution handler committed. Should
be transfering full distributions over in the next commit.
