Package: partmen-efi Severity: serious Tags: d-i Not sure if partman-efi is the right place for this bug to be filed, but it's where things are showing up. Maybe parted is a better place?
Older versions of the installer (up to and including at least jessie d-i alpha 1, 2014-03-18) use the correct GUID for an EFI system partition on GPT, C12A7328-F81F-11D2-BA4B-00A0C93EC93B. Later versions (including jessie d-i beta 1, 2014-08-13) are using 0FC63DAF-8483-4772-8E79-3D69D8477DE4, which is "Linux filesystem data". This is wrong and will cause installation failures on some machines if they're conforming correctly to the UEFI spec. See [1] for more information. Using snapshot.d.o, it looks like the most likely cause of the breakage is the switch from parted 2 to parted 3. I'm looking deeper now.
