* Files added for fully automated creation of RAID system. These files should be copied to /etc (except maybe mkraid.sh) to a Debian system with RAID kernel support and raidtools2 package installed. The source harddrive MUST be /dev/hdb and the two RAID-1 drives MUST be /dev/hda and /dev/hdc. The two RAID harddrives MUST be partitioned like this : /dev/hda1 and /dev/hdc1 MUST be swap (type 82). /dev/hda2 and /dev/hdc2 MUST both de raid-autodetect (type fd).

	After this is done, just run mkraidfs.sh and sit back and play a game or two on you PDA if you have one :-).
	Mail me for questions.
