AFAIK, not a shell-script (although variables are set in that syntax).
I wasn't trying to do exactly what you are, but one thing I did was set the
MAC address as one of the bhyve options:
...
-s 5,virtio-net,tap2,mac=00:01:02:03:04:05
...
(Changed the MAC address in the example, but pick a safe one for your setup)
Should be able to provide your own rc.d configuration file that does
something like do a switch on MAC and call the hostname script directly.
