Issue #3033 has been updated by Todd Zullinger.

Markus, using another directory would indeed help ease SELinux concerns AFAIK.  
As Dan Walsh (the main selinux-policy maintainer for RHEL and Fedora noted in 
"Fedora bug #553565":https://bugzilla.redhat.com/show_bug.cgi?id=553565:

A similar bug is what prompted us to inquire about tightening the permissions 
on /var/run/puppet, which defaults to 1777.  We now patch that in the packages 
for Fedora and EPEL, as we can ensure that the needed user/group exists.  

If puppet were to use a dir that only the puppet user had write access to for 
such files, I believe that would allow selinux-policy to allow the actions it 
is now denying.  If everything using files in /tmp used the Tempfile module, we 
could perhaps even just set the TMPDIR env variable and make it easily 
configurable for folks.

Bug #3033: Using temporary files in /tmp to comunicate with child processes is 
problematic in SELinux
http://projects.reductivelabs.com/issues/3033

Author: Markus Roberts
Status: Investigating
Priority: Normal
Assigned to: 
Category: exec
Target version: 0.25.4
Affected version: 0.25.2
Keywords: 
Branch: 


The present approach is necessitated by the more common / severe locking and 
race conditions that arise when trying to implement a cross-platform solution 
based on pipes (see related tickets, below).

There are two possible solutions here, both should be explored:

* Try to diagnose why the code developed on #3013 failed as described on #3025
* Perhaps more pragmatically, see if moving the temp files presently used in 
lieu of pipes to some other directory would placate SELinux.
