Thanks for the example, did not yet have look at wg-quick.

But I argue that the concept of configuration and state should not be mixed.
Having the configuration the same and saving the current state, not
via showconf which should be used for configuration and not state as
the name implies, to a different location and restoring that state
(the current endpoint of the roaming peers) would be much cleaner and
not mix up a state-store-operation that stores a so called
configuration mixed with state that includes the private key.
