Description of problem:
Tried to play a track with mpd.
SELinux is preventing 6F75747075743A4D792050756C7365 from 'map' accesses on the file 2F6D656D66643A70756C7365617564696F202864656C6574656429.

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

If you believe that 6F75747075743A4D792050756C7365 should be allowed map access on the 2F6D656D66643A70756C7365617564696F202864656C6574656429 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 '6F75747075743A4D792050756C7365' --raw | audit2allow -M my-6F75747075743A4D792050756C7365
# semodule -X 300 -i my-6F75747075743A4D792050756C7365.pp
