I am inviting the strengthening of his position in order to better understand it. I asked him to elaborate because as near as I can tell there is no hard dependency on any D-Bus broker. There is possibly--I genuinely can't tell from the documentation I've been browsing through--a dependency on a D-Bus broker. Requiring a D-Bus broker does not make any one D-Bus broker mandatory...and so, if that is the case, then my assertion that journald is the only non-PID1 part of systemd that is required would hold.

I'm happy to be corrected if I'm wrong. I invited it, even; I'm wrong all the time and being wrong is how one learns. The big-timing I referred to is the refusal to materially engage. Instead he quotes Lennart about D-Bus--out of context? who knows! It isn't an indication of the state of the software in question, just his opinion at a point in time--and to tell me to go read (read what, exactly? what generosity in citation!). Oddly enough, though, I don't see you tagging in to lecture him about that sort of sneering. Why's that?
