I think in the majority of cases we don't need an unsupervised init
script (what's the rationale for having it in that MR (and what MR are
we talking about? :D)), since supervision has many advantges, as
mentioned in the thread already. IMHO it'd be best to just switch as
much as possible over to supervise-daemon before 3.13. I'd rather not
maintain two different sets of init scripts if possible.
