Speaking of SU+J:

I do happen to be running 9.0-BETA1, and am seeing output from fsck
where it at first appears it's going to take advantage of journaling
and then dismisses it due to an out-of-date journal (which is why I
started investigating gjournal in the first place).

Am I doing something wrong here?  Can anyone recommend a fix?
