Just when you think you have all the init systems handled, found more, #dinit (available to test in #Artix live cd), with #dinitctl, now fully handled. #Hummingbird, untested, but added in theory. #31init added in theory, that's a 31 line C init system!

Fixed some weaknesses with #OpenRC handling as well, was failing to detect it as owner of /proc/1/comm 'init' value, using readlink to test now for dinit as well.

Refactored the init section too, to fit with current internal coding style.
