strict patch

[Russell Coker <russell@coker.com.au>]

[-- Attachment #1: Type: text/plain, Size: 402 bytes --]

The attached patch has a bunch of minor changes which are mostly needed in a 
"strict" configuration when running with systemd.

It also removes the systemd_analyze_t domain which doesn't provide any 
benefit.  This patch is against the git refpolicy from 3 days ago and I think 
it's ready for merging.
