Thanks for your patch! I am wondering if adding an option for this is
needed. Can't we just enable systemd support when BR2_PACKAGE_SYSTEMD=y?

I think the fact that your comments is worded as "The systemd backend
needs systemd" is a good hint that this dependency is obvious, and
there's no need to have an explicit option for it.

Is there another sd-bus-provider option value that should be set when
systemd is not available?
