I recently got into a situation where it would have been convenient to put a "system" disk for one computer (a disk with Grub boot, a Linux image, and the disk partitions) into an external enclosure, plug that into a USB drive of another computer, then get that computer to boot from the external disk.
This leads me ask these questions. I hope that the answers are well-known. 1. Once the computer chain-loads the boot from an external disk, I assume Grub is smart enough to fetch phases 1.5 and 2 and the boot image from wherever it was loaded. 2. If grub.cfg on the external disk is written to locate the the partition using UUIDs or other location-independent identifiers (as opposed to sda1, etc.), Linux can boot up. 3. Is there a way to write grub.cfg to locate bootable drives attached to USB ports, offer them in menuentry's, and chain-load them? 4. Bonus points: Is there a way to load a USB stick with Grub and such a grup.cfg so that one can boot a computer off of the USB stick, from the menu, select an external disk, and get that Grub to chain-load the Grub off the external disk?
