Accepting request 303792 from home:puzel:branches:Base:System - Update to parted-3.2; Notable changes: - Added new partition type flag, esp, to set the type to 0xEF on MS-DOS. Also aliased to boot on GPT to set the UEFI ESP GUID. - You can now choose to ignore errors about partitions that overlap, or are longer than the disk. This allows you to use parted to repair the problem. - When attempting to manipulate a mounted partition, parted now issues a warning that you can choose to ignore, instead of an error. - When creating a loop label, it automatically comes with a partition using the whole disk. - parted -l no longer lists device-mapper devices other than dmraid whole disks. - Added new Linux-specific partition GUID type code (0FC63DAF-8483-4772-8E79-3D69D8477DE4) for Linux filesystem data on GPT disks. This type code is now assigned as the default partition type code for new partitions holding Linux filesystems. - Added new "msftdata" flag to identify partitions holding NTFS or FAT filesystems on GPT disks. This flag corresponds to a GPT type code of EBD0A0A2-B9E5-4433-87C0-68B6B72699C7 ("Microsoft Basic Data"). Since Linux filesystem partitions formerly used this type code, this flag may optionally be set on Linux partitions to make the partition table type codes match former configurations in case the new Linux filesystem type code causes problems with some utility. Note that this flag cannot be removed from NTFS or FAT partitions within parted except by setting a competing flag, such as "boot" (which sets the type code used by EFI System partitions) or "msftres" (which sets the "Microsoft Reserved" type code).
