You stick the command for the script in your rc.local?
Just real quick (i left my program days 12 years ago for accounting/computer
forensics, so bare with me) I know the find command, what does the -group
video do? I mean I get that it's putting whatever the find command finds
into /tmp/wfv and then if there is an entry for video1 breaking, just don't
understand the -group video option.
