Description Nilesh Parmar 2016-11-20 09:05:37 UTC
Description of problem:
augenrules includes files ending in regexp "rules" into auditd rules.

Version-Release number of selected component (if applicable):
audit-2.4.1-5.el7 

How reproducible:
Always

Steps to Reproduce:

]# cat /etc/audit/rules.d/mkrules 
-w /etc/hosts -p a -k monitor-hosts

]# service auditd restart
Stopping logging:                                          [  OK  ]
Redirecting start to /bin/systemctl start auditd.service
[root@dhcp9-127 ~]# auditctl -l
-w /etc/hosts -p a -k monitor-hosts
