    /news crashed on crater.  A few days were lost relative to
    my last backup.
Well if we had ZFS this was almost zero problem ;-)
By the way how is progress going for the fundamental layers in that 
area? Because most of the technical explanation are way over my 
competence I don't get the fine details of it, anyone care to give some 
insights on what the progress is/which are the hairy parts, in a 
language that me, a simple administrator with no kernel coding 
knowledge, could comprehend with careful reading?
