slim:

sv start dbus || true
sv start elogind || true

But 'sv start' will run the check script, won't it, which now tests a
dbus 'ping'.

So probably on my system it is what we (I) recently added [1],

docker:

sv start elogind

But I don't think we want to start encoding transitive dependencies
which aren't also first class dependencies, so I think we just divert
stderr in the dbus check file as you first suggested!
