really not having a lot of luck. /etc is missing, /var is missing,
I'm not finding a lot of files in the lost+found directory. life is
not good. I managed to find my ivtv config file and I'm still poking
in a few other directories but it's not real promising. i found some
of the log files and I guess there were some database issues 3-4 days
in advance of the failure.
