Description of problem:
Note: This is very similar to bug 1293744, just for a different command.


Version-Release number of selected component (if applicable):


Steps to Reproduce:
1. Set up an acpi handler and corresponding script
2. Have that script try to use 'pactl' to alter the mute status, etc.

Actual Results:  
The script fails, if SELinux is being enforced.

Expected Results:  
The script succeeds, just as it does when SELinux is disabled ("setenforce 0")

With the below local policy, it works as expected - I can, for instance, change the mute status as a result of an acpi event (such as pressing a special key on my keyboard).

There were quite a lot of AVC denial log messages, and some info that is private for my system, so I have not included those.

However, the .te file that audit2allow created is below:

------------

	class file { read lock create write getattr unlink open };
	class sock_file write;
	class dir { search setattr read write getattr rmdir remove_name open add_name };
}

Original discussion of why I am attempting to do this in the first place is on this pulseaudio thread: http://lists.freedesktop.org/archives/pulseaudio-discuss/2015-December/025060.html
