Ok. :-)

The problem is that changing a live fs from small inodes to large inodes
requires shuffling a LOT of information around. A program which could do
this safely would need a LOT of work, and testing. Much more than can be
done for 1.4.

The safest thing to do would be to dump, newfs -L, restore. But a
migration utility might be interesting later. :-)

Take care,
