Description Charlweed Hymerfan 2014-03-25 16:42:28 UTC
Description of problem:
Fresh new install of Fedora 20.
SELinux is preventing /usr/sbin/chronyd from 'write' accesses on the sock_file .

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

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