As of the new polkit commited to Tumbleweed/Factory (as of 20231206), polkit
explicitly "Requires: /usr/bin/dbus-daemon" [1] insted of the previous dbus-1.
With this other dbus implementations, such as dbus-broker are left out,
breaking systems with such dbus implementations:
"Problem: das zu installierende polkit-123-1.1.x86_64 erfordert
'/usr/bin/dbus-daemon', aber diese Anforderung kann nicht bereitgestellt
werden".
For an intermediate solution, the Requires could be changed back as the
changelog only states: "Add /usr/bin/dbus-daemon BuildRequires, needed for
tests. Replace the dbus-1 with /usr/bin/dbus-daemon Requires." So the explicit
requirement should only be added at build time.
