Description of problem:
This pops up after the login on a live system (Fedora 20160220 Rawhide Workstation)
SELinux is preventing systemd-logind from 'write' accesses on the fifo_file 21.ref.

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

If you believe that systemd-logind should be allowed write access on the 21.ref fifo_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 systemd-logind /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
