Description of problem:
when dnssec-triggerd ran, as a staff_t confined user.
SELinux is preventing /usr/sbin/unbound-control from 'write' accesses on the file /run/dnssec-trigger/lock.

*****  Plugin leaks (86.2 confidence) suggests   *****************************

If you want to ignore unbound-control trying to write access the lock file, because you believe it should not need this access.
Then you should report this as a bug.  
You can generate a local policy module to dontaudit this access.
Do
# grep /usr/sbin/unbound-control /var/log/audit/audit.log | audit2allow -D -M mypol
# semodule -i mypol.pp

*****  Plugin catchall (14.7 confidence) suggests   **************************

If you believe that unbound-control should be allowed write access on the lock file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep unbound-control /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
