Description

On linux we currently store the root owned plugin keyfile in /etc/electrum/plugins_key, however the /etc directory may not work on some distributions like NixOS and Fedora Silverblue as there the /etc directory is read only or its content can get deleted on system rebuilds/updates.
Is there a reason why we can't just store the keyfile in config.electrum_path() or alternatively at $HOME/.config/electrum/?
