IIRC Ramakrishnan doesn't have a working 9pi system.

I put 9pi with this patch in contrib/bakul on sources. It was
cross-built on a 386 VM with a pull done this morning + the
above patch. I had to rebuild the host 5c due to rune related
errors so I am not 100% certain this will work (I probably
should've done a full rebuild of the host binaries too).

He should be able to mount the dos partition on another
machine and replace 9pi on it.
