Hi, I'm new here so I'm not sure if the topic has been discussed before. I am working on a Debian 9 / GNOME system with read only filesystem. Changes to the network settings (e.g. via nm applet) are therefore lost when restarting the system. The question now is, where does the NetworkManager store the information about which network connections have been activated in order to be able to persistently store this location?
Hi, The state of NetworkManager is stored to /var/lib/NetworkManager. I think you should just mount this directory (or /var/lib entirely) as a tmpfs. Regarding connection profiles in keyfile format. Set keyfile.path to something like /var/run/NetworkManager/profiles.d (and possibly use systemd-tmpfiles to create the directory). See `man NetworkManager.conf`. best, Thomas
