There are rules in the policy which allow dbus communication only in one way while iboth directions should be allowed.

This bug was initially created as a copy of Bug #2154245

I am copying this bug because: 



Description of problem:

RPM scriptlets (rpm_script_t) can execute hostnamectl, but systemd-hostnamed is not able to reply:
-------- 8< ---------------- 8< ---------------- 8< ---------------- 8< --------
# sesearch -A -s rpm_script_t -c dbus -t systemd_hostnamed_t
allow dbusd_unconfined nsswitch_domain:dbus send_msg;
allow dbusd_unconfined systemd_hostnamed_t:dbus send_msg;

# sesearch -A -t rpm_script_t -c dbus -s systemd_hostnamed_t
--> nothing
-------- 8< ---------------- 8< ---------------- 8< ---------------- 8< --------

Please make sure that every DBus message sender can get replies, it's very likely that such issue applies to other system components.

Version-Release number of selected component (if applicable):
