apache 4.1 & SELinux on FC6

[phil]

List,

I'm performing a bit of an experiment setting up some software on FC6 
and confining it in an SELinux domain.  In taking a survey of potential 
obstacles, I've run into something that I'm hoping y'all can provide 
some guidance on.  The application I'm setting up was initially deployed 
on RHEL4 (SELinux disabled) and thus depends on MySQL (version 4.1).  In 
developing policy I'd really like to use the most up to date modular 
policy from FC6 (anticipating our transition to RHEL5), but the MySQL 
packaged in FC6 is 5.0.

 From my perspective, my options are:
(1) try using MySQL 5.0 and hope the application doesn't break (cross 
your fingers)
(2) install MySQL 4.1 (from source / older package) and try to use the 
FC6 policy for MySQL 5.0 and hope that works.

I'm not really sure which is the best choice (though option 1 does seem 
like higher risk) so I thought I'd ask for some advice.  Has anyone used 
the FC6 MySQL policy with older versions of MySQL?  Am I nuts for even 
trying this?

There's another team working to bring this software up to date for 
deployment on RHEL5 but naturally our efforts are in parallel so I can't 
benefit from their work just yet (nor can I, or do I want to monkey 
around in their Java code).  I could always develop my policy on the 
older RHEL4 platform and use our standard build but when integration 
begins that would put me way behind the ball as (from what I understand) 
the policy in RHEL5 is vastly improved / different, which is why I'm 
trying to use FC6 in my initial tests.

Any help / guidance / insight would be much appreciated.

TIA,
- Philip
