AVC denial with bugzilla from epel

[Tony Molloy]

Hi,

I'm installing bugzilla from epel-5 onto a Centos-5 Server. I'm getting the 
following AVC denied message:

Summary
    SELinux prevented httpd reading and writing access to http files.

Detailed Description
    SELinux prevented httpd reading and writing access to http files. 
Ordinarily
    httpd is allowed full access to all files labeled with http file context.
    This machine has a tightened security policy with the httpd_unified turned
    off,  This requires explicit labeling of all files.  If a file is a cgi
    script it needs to be labeled with httpd_TYPE_script_exec_t in order to be
    executed.  If it is read only content, it needs to be labeled
    httpd_TYPE_content_t, it is writable content. it needs to be labeled
    httpd_TYPE_script_rw_t or httpd_TYPE_script_ra_t. You can use the chcon
    command to change these context.  Please refer to the man page "man
    httpd_selinux" or http://fedora.redhat.com/docs/selinux-apache-fc3 "TYPE"
    refers toi one of "sys", "user" or "staff" or potentially other script
    types.

Allowing Access
    Changing the "httpd_unified" boolean to true will allow this access:
    "setsebool -P httpd_unified=1"

    The following command will allow this access:
    setsebool -P httpd_unified=1

This seems to a denial to r/w a file in /tmp

I can generate a local policy to allow this access with audit2allow but what 
is the correct way to handle this.
