The trick there is you take the relevant configs and serialize them to disk periodically, and then in a bootstrap scenario you use the configs on disk.

Presumably for the infrequently read configs you could do this so the service with frequently read configs can bootstrap without the service for infrequently read configs.

Like a backup generator for inputs. Makes sense.

Yes, this is how I have set up systems to bootstrap.

For example a service discovery system periodically serializes peers to disk, and then if the whole thing falls down we have static IP addresses for a node and the service discovery system can use the last known IPs of peers to bring itself back up.
