This is a good point. I didn't think of this. The same for Jorgen
Lundman's remark about adding jornaling to FFS like a mount option just
like softdeps.

Matt: Go for it! :-)
(One thing to take into consideration: It may be more valuable to have
jornaling for FFSv2 first, then for FFSv1. A FFSv2 can be much larger
then a FFSv1...)
