I am setting up a local NixOS container to separate some processes from my main machine. I am entering the container using machinectl shell, so I do not need a login prompt at the “console”, yet there is a agetty process running:
~ $ machinectl shell jojo@dev /usr/bin/env ps -A
Connected to machine dev. Press ^] three times within 1s to exit session.

Connection to machine dev terminated.
In the interest of running as few processes there as possible, is there a (easy, supported) way to disable the agetty there?
