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.
