well, at the risk of seeming curmudgeonly, I can play Devil's Advocate
and point out that you already have full control over this, all you
gotta do is make a full backup before you do the installation. Use
'dd' to make a bitwise image of the partition (or drive) then if the
updgrade/installation fails, just use 'dd' to pour the bits back in 
place.
