FS#611 - dnsmasq Ignore resolv file option forget at restart
User who did this - howl (howl)

----------
One last appointment, when resolvfile is empty it doesn't touch /etc/resolv.conf, but /tmp/resolv.conf instead. So the workaround that removes /etc/resolv.conf symlink and set it up as a text file with search lan nameserver 127.0.0.1, is valid and makes it possible to use the dnsmaq luci util because despite it blanks resolvfile option doesn't matter, as it edits /tmp/resolv.conf, leaves /etc/resolv.conf untouched, and uses /etc/resolv.conf file despite it should use no resolv.conf file.
