I am curious to know how easy it is (or not) to have the newish Advanced format [1] support in Debian-installer [2], as well as the ext* filesystems [3]. I remember a story about it which came in osnews[4] long-time back (around 1.5 years +) but do not really know how relevant they are or not atm. I am asking as from what i read alongwith the above at the very least the perception is most of the changes being done are to take care of growth for the next 20 + years. I also saw discussions on the linux kernel page [5] but that wiki page is not current with the linux 3.x kernels. I did however spot an article on lwn.net [6] . Sadly there is no wiki entry about 'Advanced Format' on the Debian wiki. It would be nice if somebody has some updated instructions for it somewhere. > Finally one would have to explore the chances to get Debian bootable > ISO images onto GRUB2 rather than ISOLINUX. > > Then one would develop a friendly fork of grub-mkrescue as proof-of-concept > of the various bootabilities in one single ISO image: > - amd64 BIOS from CD > - amd64 BISO from USB stick > - amd64 UEFI from CD > - amd64 UEFI from USB stick > For this we'd need to enhance xorriso by GPT production. > > > Alternatively one could find out how far SYSLINUX is with UEFI support. > > Or whether a ISOLINUX BIOS setup can be combined with a GRUB setup > in a FAT partition.
