It looks like James (with some help from Thomas) has worked out a
quick way to change things to make things better for you, which is
good! (Thanks, guys! I'm about to test the change locally.)
*However* you're the *only* person I've seen complaining about this
problem with "file system transposition". I genuinely have not seen
issues raised by people doing this, except where (it seems) Rufus is
working this way. Let's be clear: "transposition" == "copying things
onto a less capable filesystem". I'm normally really impressed by your
skills and knowledge, but I don't understand why you seem to be so
obsessed by this.
With some tweaks like this MR, simply copying files onto FAT32 can
clearly be made to work for UEFI-only media. That's fine. But it still
breaks other useful features, at least:
* BIOS boot
* image checksums
and those are important for me and a lot our users. Seriously, just
using DD or similar gives people a verifiable, known-good copy of our
installer image that will boot on as many machines as possible and
work well in the debian-installer environment. That's my primary goal
here.
