Here's the script I use to delay until the udev permissions are set on my
tuner (ie group is video instead of root). I post this because A) it
might help you and B) if anyone has a better way of doing this I'm
listening. I'm a programmer but not a bash expert. It seems like this
should be possible without a temp file but I couldn't get it to work and
it was getting late the night I was messing with it. I'm sure there are
other ways to check permissions, too.
#!/bin/sh
while true; do
find /dev/video1 -group video > /tmp/waitForVideo
if [ `grep video1 /tmp/waitForVideo` ]; then
break
fi
sleep 1
done
