Tunneling 9P over SSH with plan9port

This gist documents a working pattern for exporting a filesystem with u9fs, listening for 9P connections with plan9port's listen1, tunneling that connection over SSH with autossh, and mounting it locally with 9pfuse. Three unshare-based namespace aliases are included for isolating the client side mount in its own mount/PID/UTS/cgroup namespace. A closing side note covers wrapping the whole thing in torsock for a zero trust transport that does not depend on the source IP being trusted.
