A signal-forwarding process manager for containers
Description
Catatonit is a /usr/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.
