Hi All,
As people might remember, we were going to have Scientific Linux 4 
follow the "legacy" path that Scientific Linux 3 took.  For those that 
don't remember, or hadn't heard, here is our news announcement on it.

http://www.scientificlinux.org/news/archive/roadmap-sl4

The problem is, that this was based on the assumption that RHEL 4.9 was 
going to be released back in November 2009.

At this years RedHat Summit, I didn't hear one mention of an Update 9 
coming out for RHEL 4.  I personally believe that it will not come out 
until RHEL 6.0 comes out, if at all.

But, just for the sake of being optimistic, let's suppose that they 
release the Beta for RHEL 4.9 next week (July).  It usually takes them a 
little over two months to get a release out once it's hit beta, that 
means RHEL 4.9 would be released in September 2010.  Then it usually 
takes us a little over two months to get our release out, so we're 
looking at December 2010.  But, just to make things even, let's call it 
January 1, 2011.

We told our users that they would get a minimum of 6 months to 
transition to SL 4.9.  That put's us at July 2011, and that is being 
optimistic.  And total support for RHEL4 and SL4 ends February 2012.

So at the very best, we would only be running in Legacy mode for 8 
months.  That's not very much time for the amount of effort the 
developers, admin's, and users will have to go through to get to SL 4.9.

Here is my new proposal.
We forget about Legacy mode for SL 4.  We continue with supporting all 
of the SL 4 releases as we currently are, up until the final day in 
February 2012.

Thoughts?  Opinions?
