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

lsblk(8):
  - this NEW COMMAND lists information about all or selected block devices in
    tree-like format.

    ultrix and unixware now.

  - supports new command line option "--show" to list partitions in new format

  - prints UUID and name for GPT and mac partitions

  - supports new command line option "--submounts" to list all submounts for
    selected mountpoint(s)

agetty(8):
  - supports new command line options "-c" and "-s" to reuse already initialized

mount(8), umount(8):
