Introduction
------------

  This article describes how to label disks using bsdlabel(8).

Method
------

  Manually create BSD label using bsdlabel(8), which can read the
  label from a file. In this example the file is "labels" and contains
  the columns: label, size, offset, fstype, [fsize bsize bps/cpg]. The
  content of the file is listed below:

    a: 1g 0 4.2BSD 
    b: 1g * swap
    c: * * unused
    d: 1g * 4.2BSD
    e: 1g * 4.2BSD
    f: * * 4.2BSD

  This example creates the following labels:

    a: 1 GB for the root file system /
    b: 1 GB for swap
    c: should be empty
    d: 1 GB for /var
    e: 1 GB for /tmp
    f: the rest for /usr

  To create the label use execute:

    # bsdlabel -R /dev/ad0s1 labels

  Note that the offset of the root partition MUST be zero else the
  system won't boot.
