In the long-run, the easiest way to run #Plan9 1e (esp on non-PC platforms) will probably be to write a simple #GNULinux server program that serves BOOTP (pre-DHCP!) + TFTP for PXE boot, and #9P of the archive tarball. But 1e uses a much too old dialect of 9P for any existing software except for 1e itself to be able to serve it. And I don't want to try to write a server for it if I don't have a client to test with.
So getting `/sys/lib/pcdisk` to boot from FreeDOS is in the bootstrapping path.
