What he is proposing, is about building our own image flavor. (make-memstick.sh) Exactly, that act, is an issue here, as it confuses sysinstall's USB detection. There are 2 remedies: 1) After loader prompt, INSTEAD of starting sysinstall (as I don't need it at all), immediately START Fixit 2) Edit /usr/src/usr.sbin/sysinstall/devices.c, at the code lines, posted below and compile sysinstall, so it could recognize USB device, on non default USB img layout.
