Bug #4527

Disable ABRT for websockify
Description
Every single request when a VNC port is occupied Foreman spawns websockify.py processes and throws PortInUse exceptions until one free port is found.
The problem is on RHEL6 ABRT for Python is turned on by default, which leads to flood of messages in syslog when ABRT tries to audit the exception:
Mar 3 16:23:06 foreman abrtd: New client connected Mar 3 16:23:06 foreman abrtd: Directory 'pyhook-2014-03-03-16:23:06-7956' creation detected Mar 3 16:23:06 foreman abrt-server[7961]: Saved Python crash dump of pid 7956 to /var/spool/abrt/pyhook-2014-03-03-16:23:06-7956 Mar 3 16:23:06 foreman abrtd: Package 'foreman' isn't signed with proper key Mar 3 16:23:06 foreman abrtd: 'post-create' on '/var/spool/abrt/pyhook-2014-03-03-16:23:06-7956' exited with 1
We should fix this upstream or disable ABRT for this particular binary (dunno how?)
I am going to implement a workaround when SELinux is turned on - it will prevent to contact the ABRT server. It will not work for non-SELinux installation tho.

Solution: mmilata advices to drop script full path to /etc/abrt/abrt-action-save-package-data into the section BlacklistedPaths using Augeas or DBus service.

Correction of the configuration file: /etc/abrt/abrt-action-save-package-data.conf

Ok I am moving this to the installer project, we can disable ABRT for given script because it pollutes syslog.
When SELinux is enabled it will prevent from passing exceptions to ABRT, but we should disable ABRT for users who do not use SELinux. Low priority.

This might get refused, we will need to either blacklist the script or push fix upstream.
