Would not have helped because it's an addc start script.

This does create the dircetory /var/run/samba and/or changes owner to 
root.root and rights to (2)755.

You can change the pid directory in smb.conf to the dircetory create by 
the upstart script. If you did not specify otherwise during configure 
/usr/local/samba/var/run is the default.
