Of course not.  UFS uses 32-bit numbers for block addresses.  IMPOSSIBLE
to reference more than 2^41 bytes.

However, "UFS2" re-implemented the same disk structures using 64-bit numbers.
Thus, it can reference 2^73 bytes in the same 'logical' method.

Wojciech simply never lets inconvenient facts get in the way of his opinions
about how everyone else should do everything.
