Plan 9 vs. 9front for rpi4

rmiller's rpi has wifi working out of the box, and also has fossil since it's the stock Plan 9. 9front doesn't have either, but does have newer userspace software and has better support for networking through the ssh(1) and security with dp9ik. If I had started over again today, I might have used rmiller's Plan 9 port for rpi4, particularly since all of Plan 9 has been MIT'd.
