    I tried Kayak, but gave up due to a bit of luck.  I happened to plug my
    CF into another machine and ran the installer again there and...it
    worked!  Identical motherboards and all, the only difference is that
    this other machine only had 4GB of memory installed whereas my main
    machine has 24GB installed.  So, for anyone having trouble with the
    installer, try changing how much memory is installed.

    Regarding Kayak, I got stuck trying to a setup a DHCP server.  The
    instructions talk about using the ISC DHCP server, but `pkg search` only
    found SUN's and `dhcpconfigure` threw a Java NullPointerException...

    Thanks,
    Kent
