Subject: main: rename process to be more systemd friendly

main: rename process to be more systemd friendly

Systemd will cleanse the system of running processes
in the hand over from the initrd to the main root filesystem,
and at shutdown.

In both cases we want to keep on chugging, so we tag ourselves
in a way that systemd won't kill us.
