  I am almost certain that this was a journal created through dd and the mount
option. The e2fsprogs I was using was one of the early sct releases from Stephen
and I am quite certain it did not include the -j options for mke2fs/tune2fs.
Failing that it would certainly be 1.21-sct, since that was the version of
e2fsprogs on this machine before I upgraded everything.

  I am not quite sure now, butI think this was an old version 1 journal
(ext3-0.0.3c on 2.2.17 or thereabouts). The next possibility would be a 0.0.5d
version 2 journal.

 I do remember that for 0.0.5 instead of upgrading to 2.2.19-pre, I patched a
2.2.18 kernel.

  Sorry, there isn't much more information on this, but my priority for this
machine was to get it running 2.4, so I quickly wiped out most traces. Let me try
and dig some more.
