SELinux is preventing /usr/bin/gpg from execute,read,open,unlink access on the file /usr/bin/gpg-agent

[tjmullicani]

SELinux is preventing /usr/bin/gpg from execute access on the file /usr/bin/gpg-agent.

*****  Plugin catchall (100. confidence) suggests   **************************

If you believe that gpg should be allowed execute access on the gpg-agent 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:
# ausearch -c 'gpg' --raw | audit2allow -M my-gpg
# semodule -X 300 -i my-gpg.pp

When creating a publication using pulp rpm publication create, I get the following SELinux logs. This does not appear to impact product functionality, it just fills up the logs.
