The end goal is to drive systemd into a direction that focuses succinctly on process management, having a portable base that can be transposed to other operating systems. Still quite some way to go, but hopefully it'll be done some day. But yeah, supplying systemd's core features for people who would like to have a conservatively developed and focused service manager that won't suddenly swallow the windowing system one day, is a key goal. Captures the gist of it.
Eventually I might transfer control to someone else and focus on my own interests. The eudev project lead has expressed some interest in us.
