@jimp:
The files in /var/etc should not be touched. They are created by the system from the data in the config, and those are what openvpn uses while it's running.
As for the config entries that can't be deleted, there is a bug in 1.2.x that sometimes causes a stray "<config>" tag in certain areas. If the blank entries are a problem, just make a backup of the config, find the "<config>" tag under the openvpn server and client settings, and restore the edited config.</config></config>
Ok, thanks, will make a note of this.
