Rudder

When installing a server on RHEL9 (ans likyly all other RPM-based systems), the postinst hangs and consumes a lot of resources, with a lot of rudder agent update processes, started in a loop until the installation crashes (too to OOM killer).

This is due to the changes made in #27687 to accomodate the HTTPS-only bootstrap process. The problem is that the policy reset cannot be made, and the creterie for avoiding the loop is the presence of a promises.cf file.

The root cause lies in differences of package installation behavior of dependencies. With dpkg, the server file are installed before the agent postinst is started, allowing the policies reset to work as expected. On RPM systems, the initial-promises folder used on root is not there, leading to a loop.
