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