It can boot USB devices - that was never the issue. But apparently it
can't boot USB devices with GPT partition tables.
So the current status is.....
o Installing directly to external USB drive with GPT partition table
results in a disk that will not boot on either of the systems I am
using to test.
o Installing to the internal drive on the newer laptop, and then using
dd to copy that to the external drive works.
----- and this apparently works because the internal drive is 120GB,
and anaconda formats it with a DOS partition table
o Because the drive is 3TB, I can't use a DOS partition table (well, I
can, but then it will only use 2TB of the disk)
o Installing directly to a 2nd external USB drive that is only 500GB,
and has a DOS partition table works, and the disk is bootable on both
systems
So I guess if I want a portable Fedora USB drive I will have to limit
myself to 2TB, as older systems can't handle GPT partition tables.
