Aside from Phillip's data point, I'll say that the older machines are, the more likely they are to require CDs for booting (instead of USB); so any changes we would make to images with the intention of supporting old/new machines differently should be done with this in mind. I.e., we already support hybrid ISOs today that work on the vast majority of machines; if we're trying to preserve support for older systems with broken BIOSes, it doesn't make sense to do this by replacing El Torito support with USB-only booting. We could conceivably add *only* USB boot support for 32-bit UEFI, without adding El Torito support, if that's what you mean. If we don't think we need to boot optical media on new 32-bit UEFI systems, which seems probable, then that combination would be maximally compatible. How easy is it to put together such an image? I guess in theory it should be the same as a regular hybrid image, without the embedded FAT filesystem being registered in the boot catalog? > BTW is there a 32-bit signed-shim available?
