And there you go:
http://skarnet.org/software/sdnotify-wrapper.c

Untested with a real systemd, because I'm not going to install a
real systemd anywhere - but I've listened to a socket on the other
end of NOTIFY_SOCKET and it appears to work. Bug-reports welcome.

I'm willing to maintain this for the time being; as long as systemd
does not gratuitously break compatibility with itself, it should not
be too hard. The goal is to encourage daemon developers to stop using
the sd_notify() interface and just write a newline somewhere; the
wrapper is just there to make this simple behaviour work with systemd,
nothing more.

I firmly believe it should *not* be packaged by Devuan. The wrapper is
meant to only be used on systemd installations, which is exactly what
Devuan is not. Devuan can advertise such a wrapper, advocate its use,
but I don't think it makes sense for it to be a part of the Devuan
distribution.

I'm providing a single C file for now. I can turn it into a complete
package tarball with configure/make/make install if there's interest.
I'm not going to make distribution-specific packages, though; that's
the job of distribution maintainers.

Enjoy!
