 Hello
 
 A patch could be as below.
 
 Note I have changed the proposed commands a bit since to match new usage
 of disklabel and to init the backing file.
 
 I just add it as a different example since it IMO serves a different
 purpose than the example with backing of /tmp/boot.flp.
 
 Btw. note my posting to freebsd-current about disklabel coredumping if
 anyones decides to try this.
