To use eap tls, 'tmpdir' must be created before server starts. This 'tmpdir' is used to store and verify client certificate, and therefore radiusd do 'chmod go-rwx'. If 'tmpdir' does NOT exists, server failed to start and default 'tmpdir' is '/tmp/radiusd'. So init script MUST create default 'tmpdir' like other directories.
