[OpenWrt-Devel] [PATCH 3/3] network/services/dnsmasq: Set the default dhcp lease file and resolv file

[openwrt at daniel.thecshore.com]

From: Daniel Dickinson <openwrt at daniel.thecshore.com>

Instead of making assumption about the leasefile and resolv file make sure
we use what the user configures, but fall back to defaults of no configuration
is specified
