k3s supports multiple datastores via Kine. If one chooses not
to use etcd (the default) by passing `ClusterInit=false` they
can also specify a different datastore overriding the default location
at `/var/lib/rancher/k3s/server/db/state.db`.
For example:
datastore-endpoint: "sqlite:///etc/kubernetes/state.sqlite3"
or:
datastore-endpoint: "postgres://blueelephant:pgrulz@localhost:port/kine
