Subject: Forward port whiterussian resolv.conf changes /etc/resolv.conf links to /tmp/resolv... 
X-Git-Tag: reboot~30097
X-Git-Url: http://git.openwrt.org/?p=openwrt%2Fopenwrt.git;a=commitdiff_plain;h=656412d1a3806d94b280a9955df528faad6aa8e9

Forward port whiterussian resolv.conf changes /etc/resolv.conf links to /tmp/resolv.conf /tmp/resolv.conf links to /tmp/resolv.conf.auto by default (which is where the ISPs nameserver is in) When dnsmasq starts, it replaces /tmp/resolv.conf with a file pointing to 127.0.0.1
