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.
