If /etc/sysconfig/network is missing, the sysvinit script whines about "no
such file or directory" when network is sourced.
	Also, the test for "if [ ${NETWORKING} = "no" ] fails out because
NETWORKING has no value; the error is: "/etc/rc.d/init.d/portmap: [: =:
unary operator expected.

	Possible solution: replace:

. /etc/sysconfig/network

	with

if [ -f /etc/sysconfig/network ]
then
	. /etc/sysconfig/network
else
	exit 1
fi

	Also, replace:

if [ ${NETWORKING} = "no" ]

	with

if [ "${NETWORKING}" = "no" ]

	Cheers.
