The policy should be pretty easy to read, though. You have one rule, "allow bacula_t systemd_systemctl_exec_t:file execute." Each word in that rule, except for "allow" is defined somewhere, and has to be loaded, so they are each individually loaded in the "require" block. > and why bacula can't do transiction between context? The easiest way to write a policy is to apply labels and run an application in permissive mode. Using the AVCs that are logged, a new policy can be generated. The short answer is, you're doing something that the people who developed the SELinux policy didn't do while writing the policy. If the thing that you're doing is standard or best practice, you might consider that a bug and file a report to have the policy extended. However, I suspect that restarting services is not a standard practice, so the local policy that you've generated is the best solution.
