As I understand it, almost all new PCs for sale today have UEFI and a
BIOS compatibility layer on top.  So this replacement has already

I recently set up a linux server and do see a need for linux to boot on UEFI without relying on BIOS. The reason is the limitations of the size of the booting harddrive. there are hacks around this (multiple MBRs) but these would upset for example a dual-booting windows. this also doesn't chime well when persuading new users to try out linux. so, in my opinion, debian should be among the first to support UEFI well and to show that linux can be first rate in hardware support.

one challenge for the installer will be how to support manual partitioning while making installation of the uefi boot partition easy. if there is none then debian should suggest to create it, with good default settings.
