Re: [9fans] 9front on raspberry pi

[Chris McGee <newton688@gmail.com>]

The GPIO doesn't have a manual page as far as I know. The implementation came from what is in 9front mainline and is in #G. I agree that it would be good to have a manual page for it there.

mDNS is running as bcast9p process and is written in Go. It's based on a Go library and uses udp multicast support for plan 9 that is only in latest git master branch, slated for Go 1.8.

Go SDK in this image is 1.7.3 though. It should be reasonably stable.
