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.
