If /usr/bin/cmp does not exist, The whole test will fail, then it will
work as heretofore.  So, I think we don't need to test if /usr/bin/cmp
exists.
However, if /usr/bin/cmp does not exist, error message will out.  So,
we need to supress it as following:

		if cmp -s /etc/resolv.conf.std /etc/resolv.conf; then
			rm -f /etc/resolv.conf.std
			return 0
		fi 2>/dev/null

Sincerely,
