Using ip/ppp on the raspberry pi's serial port connected to a plan 9 server, I can boot with rootfs coming from the server, and cpu in to the pi. Not ethernet speed but it works for experimenting.
I was only able to do this by adding a 'no authentication' option to the server side of ppp, having failed completely to figure out what password(s) to configure on each side of a ppp connection to make it work. I've used ppp in the distant past to connect to a dial-up ISP, but never used Plan 9 ppp in host mode. Can anyone with recent experience enlighten me?
