Description of problem:
SELinux is preventing avahi-daemon from 'read' accesses on the file environ.

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

If you believe that avahi-daemon should be allowed read access on the environ 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 'avahi-daemon' --raw | audit2allow -M my-avahidaemon
# semodule -X 300 -i my-avahidaemon.pp
