piCorePlayer - VPN Client

I have seen a decent howto on setting up an OpenVPN client on piCorePlayer - https://forums.slimdevices.com/showt...yer-over-a-VPN - but has anyone successfully set up an L2TP VPN client on one?

I see that there are tinycore specific L2TP extensions but I can't find any documentation on how they can be used / configured?
