Device "scsi-disk" is similar.  However, it's still used by the
scsi_bus_legacy_add_drive() magic.  Not sure that's fully deprecated,
yet.  If / once it is, we can deprecate "scsi-disk", too.  Anyway, not
your department.

Two sentences, where only the first one terminated with a period.

Let's say "is deprecated, please use", like we do in several other places.

A few iotests still use ide-drive.  Should any of them be converted to
ide-hd or ide-cd now?
