- 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
