If block devices are "trivial" to build with geom, they
should've been not removed until geom was in place.  Oh well.
I am not going to argue about this over and over and over

raised with perl-5's removal and Julian & Bruce piping up).

Too far to travel :-)

Hmm.. I don't recall Kirk McKusick's argument for removing a
buffered block device.
