No need for that if you use k3b.  I haven't tried it in FC6 yet, so can only 
speak up to FC4.  D3b uses/used md5sum instead of sha1sum, but the principle 
is the same.  It calculates the md5sum of the .iso file, burns the disk, 
then, assuming you have set 'verify' it calculates the md5sum of the disk.  
If they match you have a winner - and providing you use burnfree and don't 
burn too fast most times they will match.
