[GSoC24 Weekly Status #8] rusers

This week, I ported version 3 of "rusers" and "rpc.rusersd" (
https://reviews.freebsd.org/D45988). My mentor, Li-wen, advised me to
provide more detailed information about the testing process in Phabricator.
Initially, I was concerned about the difficulty of testing due to the lack
of an RPC server. However, Li-wen suggested that we could use a jail to
simulate both the RPC server and client on a single machine. I plan to use
this setup to test the RPC programs.

Best Regards,
