playman@ubuntu-ghost:/etc/samba$ sudo /etc/init.d/smbd restart
Rather than invoking init scripts through /etc/init.d, use the service(8)
utility, e.g. service smbd restart

Since the script you are attempting to invoke has been converted to an
Upstart job, you may also use the restart(8) utility, e.g. restart smbd
smbd start/running, process 17574
