Update....
I was able to create a working "portable" USB disk by installing on
the *internal* disk, and then dd'ing it over to the USB disk (and
zero-ing the internal disk to make sure it didn't boot from there).
However, a 2nd older system still does not see the USB disk as a boot
device. I'm thinking this might be because anaconda is creating the
partition table as GPT, and the older system might not understand it?
As a test, I am trying again with a 2nd disk with a DOS partition
table.
Not all systems are capable of booting USB devices. It depends on the
age of your BIOS and the hardware. Get into your BIOS' boot selection
section and verify you can, indeed, select USB devices there.
