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. -- Grant Edwards grant.b.edwards Yow!
