Description of problem:
With SELinux in enforcing mode, the unbound-munin plugins don't work out of the box.

Version-Release number of selected component (if applicable):
1.4.16-2.el6

How reproducible:
Always

Steps to Reproduce:
1. Have selinux in enforcing mode
2. install unbound-munin and start munin-node
3. try to get the unbound stats
  
Actual results:
No stats

Expected results:
stats are collected

Additional info:
To fix it, one can manually change the type of /usr/share/munin/plugins/unbound to munin_system_plugin_exec_t, and allow munin_system_plugin_exec_t to read the unbound config file:

allow munin_system_plugin_t named_conf_t:file { read ioctl open getattr };

It would be nice if either unbound-munin supplied this, or it would be included in the default policy.
