- Moved from openvpn package to tun package - TUN check verifies Rdev value - TUN create - Inject as interface to main function - Add integration test - Clearer log message for end users if tun device does not exist - Remove unix package (unneeded for tests) - Remove tun file opening at the end of tun file creation - Do not mock unix.Mkdev (no OS operation) - Remove Tun operations from OpenVPN configurator
