Rudder

In the Synchronization method from Relay servers page if you choose rsync and do not select an option (so manual rsync) when hovering over each of the two prompts they imply that you only need to sync /var/rudder/share to the relay and not /var/rudder/share/{relay-uuid}.

I would recommend adding either this Rsync command to the docs and referencing the docs via the prompt in the screen shot or showing the user command like below:

Shared Files:
*/5 * * * * rsync -avz -e ssh --archive --checksum --compress --sparse --delete /var/rudder/configuration-repository/shared-files/ root@relay:/var/rudder/configuration-repository/shared-files/

Relay Policies:
*/5 * * * * rsync -avz -e ssh --archive --checksum --compress --sparse --delete /var/rudder/share/{UUID-OF-THE-RELAY}/share/ root@relay-xyz:/var/rudder/share/
