- update to parted-3.1 (fate#316110) - changes in parted-3.1: * Changes in behavior - Floppy drives are no longer scanned on linux: they cannot be partitioned anyhow, and some users have a misconfigured BIOS that claims to have a floppy when they don't, and scanning gets hung up. - parted: the mkpart command has changed semantics with regard to specifying the end of the partition. If the end is specified using units of MiB, GiB, etc., parted subtracts one sector from the specified value. With this change, it is now possible to create partitions like 1MiB-2MiB, 2MiB-3MiB and so on. * Many bugfixes (see changelog) - changes in parted-3.0: * Changes in behavior - Remove all FS-related (file system-related) sub-commands; these commands are no longer recognized because they were all dependent on parted "knowing" too much about file system: mkpartfs, mkfs, cp, move, check. - 'resize' command changed semantics: it no longer resizes the filesystem, but only moves end sector of the partition - libparted-devel contains libparted-fs-resize library - add ability to change size of the partition (ignoring contained filesystem) with 'resize' command; this command has different semantics than the former 'resize' command which upstream decided to drop - parted-resize-command.patch (fate#316110) - when using syncmbr on POWER, make the first partition type 0x41 OBS-URL: https://build.opensuse.org/package/show/Base:System/parted?expand=0&rev=79

Subject: [PATCH] GPT: add support for PReP GUID
PReP (PowerPC Reference Platform) boot partition is the first partition used in
PowerPC platform for containing the bootable kernel or bootloader. The firmware
searches for this partition and jumps to it for booting. So far no GUID was
specified for this partition type and hence booting from GPT disk was not
supported on this platform. A new GUID 9e1a2d38-c612-4316-aa26-8b49521e5a8b for
PReP partition is proposed to be included in GPT.
