Yes.  Block devices are a quaint relic of the past, and aren't
needed. :)

Yes, on FreeBSD, just use the char dev.

: always char devices.  For the other BSDs and Solaris do we allow only

: O_DIRECT for block devices nodes which pretty much is a Linux-ism so
: for cache=none at least we should probably open the raw nodes..

Other BSDs still have block devices.  O_DIRECT is supported in at
least NetBSD (and FreeBSD).
