Error in /etc/init.d/opendnssec-signer on ubuntu

service opendnssec-signer status always returns "not running". The problem occurs because the pid file is stored in /var/run/opendnssec,rather than /var/run.

Easiest way to fix it seems to be to change the call to status_of_proc in the status) case from
status_of_proc "$DAEMON" "$NAME" && exit 0 | exit $?
to
status_of_proc -p $PIDFILE "$DAEMON" "$NAME" && exit 0 | exit $?

A similar fix should be applied to /etc/init.d/opendnssec-enforcer, althohg it manages to work in spite of the pid file not being found, because the named $DAEMON is still running when the status check is made. This is not the case for the singer.
