I'm going a different way: I've implemented signal handling in my runvdr
itself. That way I can kill runvdr, and runvdr will kill vdr, and of
course knows that vdr doesn't need to be restarted.
Simplified, it works like this:
trap "SIG=TERM" SIGTERM
# run vdr
eval "$VDRCMD" &
# wait for VDR terminating or signal caught
if [ "$SIG" = "TERM" ] ; then
# runvdr was killed
# dont restart
# normal termination, decide on errorlevel $VDRRETURN
