Prosody needs some SELinux love:

SELinux is preventing /usr/bin/lua from write access on the directory prosody.

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

If you believe that lua should be allowed write access on the prosody directory 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 lua /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Now I know why I was not getting any logging at all.  ~sigh~
