uplink: Call res_init after resolv.conf changes #72

Closed hessu closed 2 years ago

hessu commented 2 years ago

Older glibc versions have a bug where resolv.conf is not reloaded after it changes. Debian distributions have been shipped with a patch to work around the bug, so this likely only affects other distributions.

Hopefully fixes #68.

Thanks!

It seems not to be a recent bug (https://sourceware.org/bugzilla/show_bug.cgi?id=984).
