I remember doing some superblock conversion on -current; I didn't do 
anything like that when I upgrade my laptop from 1.6.2 to 2.0beta.  But 
I'm seeing this message during the boot process:

	/: correcting fs_sblockloc from 0 to 8192

I don't see any such message for /usr.  What, if anything, is wrong, 
and what, if anything, should I do?
