  | Well the default is 4 fragments per inode, you only need FFSv2 for
  | more than 2^31 fragments - so any filesystem that needs FFSv2 is
  | close to needing more than 2^31 inodes.

Huh?   If I have 2^16 files, each 2^32 blocks, how many inodes do I need?
And how do I fit that all on a FFSv1 ?

  | (or if 2^31 inodes is way plenty, why do we need 2^31 fragments?)

Not all files are minimum sized (or default bytes/inode sized).
