Well I initially installed via Gentoo, which I believe was based on 1.1
code (April 2002).

I was just hoping to dump and restore this filesystem onto an identical
adjacent (move from hda8 to hda7) in order to grow hda7 to the entire
size of the two partitions.

But I guess either I didn't compile the utils right or the filesystem on
disk is still in the older V1 format.

This if for no other reason would be a good reason for a point release
that contains the V2Log code, if the future utilities aren't going to be
able to cope with V1.  Or is there an easy way to convert?
