I'm considering purchasing a USB 2.0 IDE drive enclosure. My motherboard supports booting from USB. Can I install FC3 to the USB drive, e.g. as /dev/sda? I'd like to have my full FC install on a portable drive, so that I can take it with me. I have an existing OS on my main desktop that I don't have the liberty of modifying at the moment and being able to run FC on demand would be great. Thank you.
