Jordan K. Hubbard 4d7b3c6f96 1. Primitive bad144 support (I believe an additional command is needed, but
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.
