  That looks good. The "boot" command doesn't actually start the VM - it 
finalizes setting register state so that usr/sbin/bhyve can then run it. 
The bhyve.org script hides that from you.

  Using "-r hd0,msdos1" will allow "ls /" to work, though the 
(hd0,msdos1) qualifier in the first example does the right thing.

later,

Peter.
