implications of httpd_unified

[Daniel J Walsh]

http_unified means, that all file types for httpd_sys_* are treated the 
same way.

httpd_sys_content_t
httpd_sys_content_rw_t
httpd_sys_script_exec_t
httpd_sys_content_ra_t


If you turn on this boolean, and you want a script running as 
httpd_sys_script_t or httpd_t can read/write/execute all http_sys file 
types.

If you turn it off, the admin is responsible to make sure the labeling 
is correct on all files.  So if httpd_sys_script_t wants to write to a 
file/directory, it needs to be labeled httpd_sys_content_rw_t.

httpd_sys_script_t can not interact with httpd_(NON sys)_content_t with 
or without the boolean set.

the httpd_unified boolean does not effect any other
httpd_(NON sys)_script_t domains.
