Postinst scripts do not set the postgres password
In 6.0 on rpm based distros, we are enforcing the postgres/ldap/etc... passwords from an agent execution done in the webapp postinst script.
This run trigger the password edit, only if the node is the "Server root" and base its detection on the existence of the "/opt/rudder/etc/server-roles.d/rudder-server-root" file which
come from the "rudder-server-root" package, which is STILL NOT installed at this time.
The password edit is then skipped...
We should change the detection to be based on file existence OR uuid=root
