How To Install catatonit on Fedora 34

What is catatonit
Catatonit is a /sbin/init program for use within containers. It forwards (almost) all signals to the spawned child, tears down the container when the spawned child exits, and otherwise cleans up other exited processes (zombies). This is a reimplementation of other container init programs (such as “tini” or “dumb-init”), but uses modern Linux facilities (such as signalfd(2)) and has no additional features.
