This is a difficult change.... 

Some GUI install things already perform this check and after asking
confirmation from the user will just execute:

	mkfs.ext3 /dev/....

and expect it to make the filesystem. 

So you could add an option: 
	--check _for_existing_filesystem

But then it is quite likely that people running it manually will
forget to add the option....
