Rudder

When we promote a node to relay and put a node immediately by following the doc, we got an error on the node:

root@cs81_ubuntu24:~# rudder agent server-keys-reset
Resetting all known keys allows the node to connect to another server than the one it is currently trusting.
Do yo really want to do it?
Type ctrl-c to abort now or enter to continue

R: Initial policies have been successfully downloaded from the policy server
ok: Rudder agent policies were updated.

It because the relay didn't download the initial policies, we should run the agent. But the documentation doesn't mention it.
