Perfecto, thanks you. :)
Aplying 055d4066 (logind: fix policykit checks) fixed the issue.

Now works as expected:

(with polkit rule to deny)
[djgera at host322 ~]$ systemctl reboot
Failed to execute operation: Access denied
Failed to start reboot.target: Access denied
[djgera at host322 ~]$

Without polkit installed at all:
[djgera at host322 ~]$ systemctl reboot
Failed to execute operation: The name org.freedesktop.PolicyKit1 was not
provided by any .service files
Must be root.
[djgera at host322 ~]$
