Hard drive install (upgrade) from USB drive?

I have done it a bunch on six machines (its how I upgrade each time). I got this from this website (http://www.duncanbrown.org/linux/system_administration/fedora_core_grub_install/)and have used it with FC5, FC6 and FC7:

1. Put the ISO on the USB device (because I have a terrible memory, I put it in the root but you can put it anywhere as long as you can remember the directory!).
2. Either grab the kernel image and initrd root image or open the ISO and extract vmlinuz and initrd.img.
3. rename vmlinuz to /boot/FC7-install
4. rename initrd.img to /boot/FC7-install.img
5. Add these three lines to your /boot/grub/grub.conf 

title Fedora Core 7 Installation
	kernel /FC7-install
	initrd /FC7-install.img

6. Reboot your machine. As it boots you have the chance to this the space bar, do so and pick the menu item called  "Fedora Core 7 Installation"
7. It will go through the normal set of questions. Once it gets to asking you where you want to install from, pick hard drive and the pick the USB drive (on every install I have done, it is the very last dive listed at the bottom). The enter the directory in the bottom box (or just "/" if you put it in the root).
8. From there it will let you pick the rest of the options.

Good luck!

Let me broaden my question a bit: Has anyone actually installed or upgraded
from an ISO file residing on a filesystem on a USB mass storage device? 
(USB CD/DVD-ROM doesn't count.)  If so, how did you boot?
