Storing the SCION path sqlite databases persistently on disk is a valid setup that improves performance, but may have outstanding bugs that need to be investigated, so this makes persisent storage optional, off by default.

This option decides whether to persist the SCION path sqlite databases

on disk or not. Persisting this data can lead to database corruption in

extreme cases such as power outage, meaning SCION fails to work on the

next boot. This is being investigated.

SCION is a routing protocol and requires bootstrapping with a manual, imperative key signing ceremony. You may want to join an existing Isolation Domain (ISD) such as scionlab.org, or bootstrap your own. If you have completed and configured the public key infrastructure for SCION and are sure this process is complete, then add the following to your configuration:
|
|
|
|
services.scion.bypassBootstrapWarning = true;
