# Purpose:      Used by dhclient-script to set the hostname of the system

#               to match the DNS information for the host as provided by

#               DHCP.

# Depends:      dhcp3-client (should be in the base install)

#               hostname (for hostname, again, should be in the base)

#               bind9-host (for host)

#               coreutils (for cut and echo)
