[Cerowrt-devel] test-ipv6.com vs dnssec

We used to arbitrarily restart dnsmasq after boot with a script.
Perhaps doing a /etc/init.d/dnsmasq reload 60 sec after boo will show

But I am puzzled as to not getting an ipv4 route. This hints at an
issue on the ubus.

I am trying to take a bit of vacation for the next week or so, it was
my hope everything was actually working...

... and even if it isn't, I need a break. Good Luck on this y'all,
I'll be back after a tan.
