I am not sure what you'd change in vmrun.sh. In -STABLE, for a reboot,
bhyve doesn't exit so vmrun.sh doesn't need to change at all.

The loop in vmrun.sh ensures the VM gets restarted if bhyve crashes
(making this optional may be useful). I am not sure what else one might
change.

I'll write to write some better documentation so that there is something
else to refer to, rather than just the vmrun script.
