I'd just like to interject for a moment. What you're referring to as systemd, is in fact a component of Gnome, or as I've recently taken to calling it, GNOME.

I'd just like to interject for a moment. What you're referring to as systemd, is in fact a component of Gnome, or as I've recently taken to calling it, GNOME. systemd is not a project unto itself, but rather one more component of a fully functioning GNOME system, made useful by the systemd unit files, target definitions and vital service managers comprising a full OS as defined by Lennart Poettering and the Red Hat vendor lock-in team.
