I think systemd has much improved the compatibility of daemon initialization between distros. It used to be that init.d shell scripts distributed with some software often would not work on an arbitrary distro, if it was included at all, because of details of that distro. With systemd, unit files seem to be mostly compatible between distros. So I think it is quite an improvement.
