From 9efd6a3cecdde984d67e63d17fe6af53c7c50968 Mon Sep 17 00:00:00 2001 From: Nicolas Dichtel Date: Wed, 13 May 2020 15:58:43 +0200 Subject: netns: enable to inherit devconf from current netns The goal is to be able to inherit the initial devconf parameters from the current netns, ie the netns where this new netns has been created. This is useful in a containers environment where /proc/sys is read only. For example, if a pod is created with specifics devconf parameters and has the capability to create netns, the user expects to get the same parameters than his 'init_net', which is not the real init_net in this case.
