Description Alex. H. F. 2015-03-07 09:08:14 UTC
Description of problem:
SELinux is preventing /usr/sbin/rsyslogd from 'unlink' accesses on the lnk_file log.

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

If sie denken, dass es rsyslogd standardmässig erlaubt sein sollte, unlink Zugriff auf log lnk_file zu erhalten.
Then sie sollten dies als Fehler melden.
Um diesen Zugriff zu erlauben, können Sie ein lokales Richtlinien-Modul erstellen.
Do
zugriff jetzt erlauben, indem Sie die nachfolgenden Befehle ausführen:
# grep rsyslogd /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
