Port BB ext script to Hobbit

[ZanDAhaR <allan (at) zandahar.net>]

Hey guys,

Just wondering what is required to port a BB ext script from somewhere 
like Deadcat over to the hobbitclient ? I've had a poke and it looks as 
it the hobbit client sets all of the old $BB variables so the script 
should be fine but Im still having troubles cos I a script newb :)

This raid monitor script is the only one I managed to get working on one 
of the boxes here so I'd prefer to stick with it. As far as I know the 
script should be fine although the line where it execs bbedf.sh 
obviously wont work so I'm assuming this is why the hobbitlaunch.cfg 
sets the ENVFILE ?

Script is attached, if anyone could have a look and let me know whats up 
it would be GREATLY appreciated

Cheers

Allan

# This script was based on bb-raid.sh, it worked for me, but I only have     #
# a single raid5 array, so your mileage may vary. Apparently the             #
# /proc/mdstat file format changed from Linux 2.0 to 2.2 to 2.4, this script #
# works on Linux 2.4.x, and may work on other versions with the appropriate  #
