After poking around across some Linuxes, it looks like people silently
agreed that "services" are not logged-in users: among the daemons,
having HOME set (as observed in /proc/*/environ) is an exception,
not the norm. I'm not sure if that's a "new" thing with systemd,
I don't have a linux with pure SysV-init available (but I guess those
are rare animals anyways).
