Building with `./configure --with-systemd && make && sudo make install` leaves `.service` files for `systemd` in `packaging/systemd`, but they don't reflect the installation location/prefix (by default `/usr/local/samba`) which needs to be adjusted manually in order to be able to use these files. Adjusting the pathes to the installation prefix shouldn't cause any trouble imo. experienced with ldb-1.1.25-258-g9790abd on Ubuntu 15.10.
