Alternatively we could just not change anything and add a smiling from the old path to the new one.

This ensures restoring a backup won't silently bring back an insecure Diffie-Hellman parameter (which could also not be inspected through the web interface anymore).

The second command will never be executed because "/var/ipfire/ovpn/n2nconf/*/*.conf” will never exist.
Because the string is quoted, the shell won’t conduct any path expansion.
What could work is running the sed command on all files simultaneously and if there is nothing to change, it won’t do anything. Passing server.conf and n2nconfig/*/*.conf will never fail if there is no N2N configuration. server.conf should always exist.
Best, -Michael
