[LEDE-DEV] Branching LEDE 17.01

[Daniel Golle]

Hi!

I'd really like to see a rather trivial issue addressed:
dnsmasq fails to get notifications on /tmp/resolv.conf.auto changes
when running inside ujail. This is because the bind mount obviously
won't survive this file being *replaced*, eg. if the DHCP client
supplies the DNS server to be used only after dnsmasq has already
been started.

The easiest solution would be to introduce a directory
/tmp/resolv.conf.d/, move all /tmp/resolv.conf* in there and bind mount
that into the jail instead. The current /tmp/resolv.conf.auto seems to
hardcoded in netifd and appears in dnsmasq's and mwan's default config.
Anywhere else? Given the overall code quality of dnsmasq, it would
really be nice to at least have it run in a jail by default for the
next release...

Mentioning the problem to John, he said that the current bind mounting
approach will be replaced by a future jailfs he is working on. However,
I'm afraid this won't be ready by Friday ;)

If there are no objections, I'll suggest a PR introducing
/tmp/resolv.conf.d/ and moving the location of /tmp/resolv.conf* into
that directory.

Cheers

Daniel
