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
