Util-linux-ng 2.17 Release Notes
================================

Release highlights
------------------

fallocate:
  - this NEW COMMAND is a command line interface to fallocate 
    Linux syscall and allows to preallocate blocks to a file.

unshare
  - this NEW COMMAND is a command line interface to unshare Linux syscall 
    and allows to run program with some namespaces unshared from parent.

wipefs
  - this NEW COMMAND is based on libblkid and allows to remove filesystem
    or RAID signatures from a device.

libblkid:
  - libblkid allows to gather information about block device topology,
    currently supported methods are:

      * ioctl - supported since kernel 2.6.32
      * sysfs - supported since kernel 2.6.31
      * fallback for DM, MD, LVM and EVMS on old kernels (base on code 
        from xfsprogs/libdisk)

    The topology support is mostly designed for mkfs programs or partitioning
    tools (already used in mkfs.xfs, mkex2fs, libparted and fdisk)
    
  - libblkid supports partition tables parsing (currently supported are
    aix, bsd, dos, mac, gpt, minix, sgi, solaris, sun and unixware). This 
    functionality is designed for mkfs programs, DeviceKits, [k]partx or so.

  - libblkid API documentation is available at
    http://ftp.kernel.org/pub/linux/utils/util-linux-ng/libblkid-docs/

blockdev:
   - supports all new topology ioctls

fdisk:
   - the fdisk command aligns newly created partitions to minimum_io_size
     boundary ("minimum_io_size" is physical sector size or stripe chunk
     size on RAIDs).

   - the fdisk command supports disks with alignment_offset now.
