parted/parted-resize-command.patch
Petr Uzel b5a4ceef04 - 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
