Description Charles R. Anderson 2016-02-20 22:46:19 EST
Description of problem:
Boot into Fedora-Live-Workstation-x86_64-rawhide-20160220.iso with enforcing=0.
SELinux is preventing ModemManager from 'read' accesses on the file passwd.

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

If you believe that ModemManager should be allowed read access on the passwd file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
allow this access for now by executing:
# grep ModemManager /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
