arigato!
arigato is a very barebones Rust framework for creating and serving a 9p
filesystem. Running on port 564 is customary; you may need to use setcap
or iptables or something to route traffic to your binary.
This currently only supports 9P2000.u; but that may change in the future.
This uses nightly-only features and isn't documented. Most of this was written
fairly quickly and carelessly to implement debugfs but I may keep this up
to date over the next few years.
Example Usage
Given an arigato 9p server running on tcp port 5641, with a mountpoint
exposed with the name foo, the following will mount it to /mnt:
$ sudo mount \
-t 9p \
-o trans=tcp,port=5641,version=9p2000.u,aname=foo \
127.0.0.1 \
/mnt
