   3 # This will format a new machine with a BOOT+HAMMER setup and install
   4 # the live CD.  You would boot the live CD, dhclient your network up,
   5 # then run 'rconfig :hammer', assuming you have a rconfig server on the
   6 # LAN.  Alternately fetch the script from a known location and just run it.
   7 #
   8 # ad6s1a will be setup as a small UFS /boot.  ad6s1d will be setup as
   9 # HAMMER with all remaining disk space.  Pseudo file-systems will be
  10 # created for /var, /usr, etc (giving them separate inode spaces and
  11 # backup domains).
  12 #
  13 # WARNING: HAMMER filesystems (and pseudo-filesystems) must be
  14 # occassionally pruned and reblocked.  'man hammer' for more information.
