udev rules, I would think

When it comes to booting from multiple devices, I've taken to installing
grub on each device, and chain load from the primary to the secondary.  So
you'd need to "grub-install" to the external (in either case - should be
just "grub-install --root-directory=/path-to-root-on-external /dev/xxx" ).
To chainload to the secondary, modify the primary's /boot/grub/menu.lst to
include:
 title   External drive
 root(hd1,0)
 makeactive
 chainloader +1

If grub is actually installed on the flash drive, then it isn't going to
care that there's no (or another) OS on the internal drive, unless you try
to select the entry for the non-existent OS.

otoh, if grub is on the internal drive (more usual), you won't be able to
boot at all if you remove the /boot directory.  So you'd need to do
a "grub-install" to the flash drive (before scrubbing the internal!).

I beg to differ, with many caveats.  If Etch is older than 2006/10 (before
feisty was synced with dapper) it shouldn't (famous last words!) cause any
upgrades to existing packages - so it shouldn't break anything that already
exists.  If it's newer than that, it still shouldn't be a problem if you
don't _let_ it upgrade existing packages.

However, many times the etch package may just not be installable, and others
it may install broken software.

Far better to just order a copy of the Gutsy DVD.
