Hi Aryeh,

> When I was playing with bhyve-grub a while ago I noticed there seemed to be
> little difference between ahci-hd and "raw" (if no format it given besides
> just naming a md file).  Is it safe to treat the two formats
> interchangeably in bhyve (and bhyve-grub)?  Can I do this to the point of

  Not quite sure what you mean here: ahci-hd is a device emulation (as 
are ahci-cd and virtio-blk). The backend for these is either a disk 
image on a filesystem or a block device.

later,

Peter.
