Wait, are you saying the start of a FAT partition will move?

It's probably not polite to say this, but CD/DVD burners are quite cheap 
these days, as is storage in general.  For something like $120 each, I 
got a pair of 250 gig hard drives.  DVD burners are more like $50, plus 
$20 gets you 100 blank write-once single-layer DVDs.

And you do know about the 75% rule, right?

This also makes me think you're saying FAT resizes both ways...

I don't work here, but believe me, they are trying.  It seems they are 
still trying to get in the mainstream kernel, which means dealing with 
lots of stubborn people...
