Strange. Looks like my init script already does this:

start() {
        ebegin "Starting upsd"
        # clean up first
        pkill -u root -x upsd
        sleep 1s
        rm -f ${pidfile}
        # now start up
        start-stop-daemon --start --quiet --exec /usr/sbin/upsd
        eend $?
}

My system is Gentoo Linux (2.6.22-gentoo-r9 kernel).

Here is my output:
