Re: [lime-users] Internet failover

Hi, I've implemented the failover functionality for babel (package babeld-auto-gw-mode) and Amuza contributed with testing. The pull: request https://github.com/libremesh/lime-packages/pull/844 I don't know if everyone know that as per our developer "guidelines" LibreMesh repository requires at least 2 approved reviews to be able to merge a pull request. I invite all those interested to collaborate by making a review :) Best!
