I had been operating under the assumption that host names and client
IDs, while not interchangeable, effectively resulted in the same
behaviors from Dnsmasq.

I had an existing dhcp-host line keyed off the host name used by the
primary interface, and it was successfully working to assign a static
IP, which suggested that my DHCP client was sending a host name, as
expected. So I figured as long as the DHCP client used for the virtual
interface sends a different host name, it ought to work.

So what's the rationale behind the different behaviors?
