I wasn't sure if these level of informations should be in commit message or not. I can add in commit message : Previously, Linux used the same GUID for the data partitions as Windows (Basic data partition: EBD0A0A2-B9E5-4433-87C0-68B6B72699C7). This created problems when dual-booting Linux and Windows in UEFI-GPT Setup, so a new GUID (Linux filesystem data: 0FC63DAF-8483-4772-8E79-3D69D8477DE4) was defined jointly by GPT fdisk and GNU Parted developers. > > include/part_efi.h | 3 +++ > > 1 file changed, 3 insertions(+) > > And without some changes to disk/part_efi.c I believe, this isn't used > anywhere so not actually changing behavior yet :) > -- > Tom > yes today the behavior don't change yet. in fact only two GUID defines is really use in u-boot code : ./disk/part_efi.c:63:static efi_guid_t system_guid = PARTITION_SYSTEM_GUID; ./disk/part_efi.c:449: &PARTITION_BASIC_DATA_GUID, 16); all the other existing value are not used today, so I add a other define not used because I don't see any simple way to use one the correct guid. I want to propose a patch to allow selection of partition type guid in command gpt (with new option guid=) but without dependancy with this patch and I plan to use this define and this new option to manage the partionning on my project.
