title: Why does `rsnapshot` repeatedly request password?
body: <p>My server configuration file has several <code>backup</code> lines that sync changes from my laptop's home directory. Since reinstalling the server OS (OpenSuse), <code>rsnapshot</code> repeatedly requests the laptop password. Passwordless <code>ssh</code> is configured and apparently working correctly - I can <code>ssh</code> into the laptop both as root as well as the regular user.</p>
  <p>How could passwordless <code>ssh</code> be properly configured yet be inaccessible to <code>rsnapshot</code> (rsync)?</p>
