   97:  - Growing the root file-system
   98:    - During the partitioning process, do not delete or format the
   99:      first MSDOS (FAT) partition, as this is what your firmware by default boots from
  100:      (unless you have prepared a boot partition on other media).
  101:    - For accident-free operation of resize_ffs, the filesystem it is supposed to grow needs to be either not mounted or at least not mounted for writing.
  102:      To do that for a root filesystem, reboot to single user, and at the prompt to enter the pathname of shell, press
  103:            return for the default (/bin/sh).
  104:    - At the # prompt, type
  105: 
  106:         "disklabel -i ld0" and press return.
  107:    - At the partition> prompt type "A" and press return.

  111:    - partition> prompt type "a" and press return.
  112: 
  113:            Filesystem type prompt, press return to use the current value (4.2BSD).
  114:            Start offset prompt, press return to use the current value.
  115:            Partition size prompt, type "$" and press return to grow the
  116:            partition to use all available free space.
  117:    - partition> prompt type "W" to save the changes to the disklabel.
  118: 
  119:            Confirm this choice by typing "y" at the Label disk prompt.
  120:            Type "Q" and press return to quit disklabel.
  121:    - At the # prompt (shell), type
  122: 
  123:            fsck -fy /dev/rld0a
  124:            resize_ffs -y /dev/rld0a
  125:    - This may take a few minutes, be patient!
  126: 
  127:            fsck -fy /dev/rld0a
  128:            mount_msdos /dev/ld0e /boot
