} Actually, as I understand ffs, it will support 2^31 fs-blocks (fragments).

What I've found by looking at the code is that mkfs() in newfs(8) checks
to see if the total number of media sectors is over 2^31. If it is, it
bails. So, if we supported sector sizes of 1024, or 2048, we'd be in
business for larger filesystems.
