We followed this:
https://wiki.samba.org/index.php/Samba4/InitScript
But it copied an html file to /etc/init/samba-ad-dc.conf. A guy on the
ubuntu forum sent us this:
/etc/init/smbd.conf
/etc/init/smbd.conf 
description "SMB/CIFS File Server"
author      "Steve Langasek <steve.langasek at ubuntu.com>"

start on (local-filesystems and net-device-up)
stop on runlevel [!2345]

respawn

pre-start script
	RUN_MODE="daemons"

	[ -r /etc/default/samba ] && . /etc/default/samba

	[ "$RUN_MODE" = inetd ] && { stop; exit 0; }

	install -o root -g root -m 755 -d /var/run/samba
end script

exec smbd -F

On disabling a ctdb node, we get an (non fatal) error:

Aug 22 00:03:40 uc2 ctdbd: 50.samba:  * Stopping Samba daemons
Aug 22 00:03:41 uc2 smbd[2398]: [2014/08/22 00:03:41.862544,
0] ../lib/util/pidfile.c:153(pidfile_unlink)
Aug 22 00:03:41 uc2 smbd[2398]:   Failed to delete
pidfile /usr/local/samba/var/run/smbd.pid. Error was No such file or
directory

I _think_ we should change /var/run/samba to /usr/local/samba/var/run

Lot's of guessing. . .
At least it's working.
Cheers,
Steve
