So Bassically all this does is create 1 (One) Rescue snapshot taken of your entire system and thats it! If you get problems, you boot to the rescue and update the Working snapshot from the rescue, and boot-back. Seems simple enough for me Bare in mind there is only 1 (One) rescue point, so if you update it! your Stuck! with It! Looks like this needs to be implimented with Rollback Rx
Bare mind, HDS specifically recommends against this. Although it can work, when I tried it there were some problems. Don't ask, I've forgotten. Pete
