- 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).

Subject: [PATCH] libparted: device mapper uses 512b sectors
|
|
|
|
device mapper doesn't use the device's sector size when creating a
|
|
table. It always uses 512b units. This causes partitions to be created
|
|
8x smaller than expected on devices with 4906b sectors.
