I did a 64-bit install from USB flash-drive a few days ago using the
older tap-dance, and it worked fine -- except I discovered one of my
"must have" apps is 32-bit only and didn't work correctly when run in
32-bit emulation mode (I don't know why).
So I tried Walter's recipe yesterday to do a 32-bit install.
After running the isohybrid command, I compared the resulting image
with the original. They were identical. I copied the image to a USB
flash drive, and it booted just fine.
It seems that the minimal install .iso images are already built for
hybrid booting from either CD or a generic block device (e.g. USB
mass-storage device).
So what's the deal with http://wiki.gentoo.org/wiki/LiveUSB/HOWTO?
Why isn't it just the steps below?
1) Copy the minimal install .iso to USB mass storage device.
2) Boot from USB mass storage device.
