To see a "complex" systemd service file, take a look at a Fedora 20
nfs-utils; nfsd is started by three lines:

ExecStartPre=/usr/lib/nfs-utils/scripts/nfs-server.preconfig
ExecStartPre=/usr/sbin/exportfs -r
ExecStart=/usr/sbin/rpc.nfsd $RPCNFSDARGS $RPCNFSDCOUNT

I would've used just one ExecStart calling
"/usr/lib/nfs-utils/scripts/nfs-server.script" but the maintainer
clearly disagrees. :)
