How to jail a single process web server on FreeBSD 12.1
You may have found many great resources on how to set up jails on latest FreeBSD, however there is scant information on how to go about creating a barebones jail with nothing but the one process that you want to isolate.
I was curious if I could contain a statically compiled web server that I wrote while learning Rust all by itself in a jail instead of having a full userland.
