auditd can halt the system for several reasons based on configuration.
These mostly revovle around audit partition full issues. I am seeing
the following denials when attempting to halt the system.

v2 - use optional rather than ifdef
v3 - fix order

Can this get merged? I have not seen any comments.
Would you prefer that I use a github pull request?
