Bug#281905: #281905 please enable CONFIG_EFI_PARTITION; it's needed for 2TiB
Christoph Hellwig wrote: Best thing for 2TB disks is to use LVM anyway At least as far as d-i is concerned (AFAICT), you have to put LVM on top of an existing partition table; you can't just use the full /dev/sda or whatever. (The command-line lets you get around this). However, even if you do use the command line to get around d-i limitations, its still not safe to have /boot on LVM (at least according to all the documentation I've seen). I believe the only way to use d-i on machines with only 2TiB disks is to rebuild the kernel to enable EFI GPT. If EFI breaks iPods, could we maybe have an 'enable_efi' kernel command-line option to enable the support? That way, everyone could be happy.

However, even if you do use the command line to get around d-i limitations, its still not safe to have /boot on LVM (at least according to all the documentation I've seen). with lilo it's safe if the LV is created with the continuous flag, for grub I'm not sure whether it has LVM support these days, I implemented support for LVM1 ~5 years ago but it got lost (and I don't have the patch anyore either) I believe the only way to use d-i on machines with only 2TiB disks is to rebuild the kernel to enable EFI GPT. Or any other of the partition formats that work. E.g. all the SGI Altix systems with 2TB volumes (which is probably all of them) use IRIX disk labels.

Partitions are in no way different from regular block devices from the kernel POV.

severity 281905 wishlist thanks The EFI format is unfortunately rather misdesigned and has a backup data area at the end of the devices - which won't be acciable by lots of usb devices because they have broken size reporting. This alone wouldn't be a problem if we could simply probe EFI last, but that doesn't work either as EFI partition tables also contain a fake dos partition table to trick around older windows versions. Best thing for 2TB disks is to use LVM anyway
