It's a shame, but this happened before I think when we went to UBC (I
think so, anyway! I don't think it was UVM). Konrad picked it up and
got it more or less working by 2, but yeah, I imagine it's not a
priority for him.

I am not aware of anything available on any of the BSDs either. I did
see something in FreeBSD about a geom journal facility, and apparently
FFS has journaling now too, but hey, it's not logging.
I was going to make a joke about putting a saddle on a seahorse, but, heh.
