SUMMARY: DHCP on boot = no default route

Thanks to those who responded.  It appears that the problem was me having a 
null /etc/defaultrouter.  I am running Solaris 5.8 and even though looking at 
the inetinit script seems to indicate that it ignores /etc/defaultrouter under 
DHCP, it still needs to not exist.  The only problem I continue to have 
is that /etc/resolv.conf only gets updated once in spite of looking at 
/etc/init.d/inetsvc and seeing that it should update it every time. Here's my 
working dhcp jumpstart postinstall subroutine (except that /etc/resolv.conf 
only gets updated on first boot and never thereafter).

	/bin/cat /dev/null > ${_ROOT}/etc/resolv.conf
	[ -f ${_ROOT}/etc/defaultrouter ] && rm ${_ROOT}/etc/defaultrouter

}

The last line of ${SI_CONFIG_DIR}/dhcp/dhcpagent:

PARAM_REQUEST_LIST=1,3,6,12,15,43



${SI_CONFIG_DIR}/dhcp/hosts:
