I have been using `--print-pid=3` as readiness notification for dbus-daemon
for quite a while now on my user services and I haven't had any problems
with it so far. IIRC, looking at dbus-daemon code, it actually prints the
socket address first then its pid. So, I use the `--print-address=` option
to save the socket address to a file for consumption by s6-envdir.
