Hello,

Thanks for your interest in Scientific Linux.  Fermilab continues to be 
the primary sponsor of Scientific Linux, with some assistance from DESY 
and ETHZ (OpenAFS and Live Media).

We plan to continue development of SL.  While the future is hard to 
predict, there are currently no indications that will change.  The 
Fermilab computing infrastructure relies on SL.

In terms of moving from 6 to 7, we recommend a complete re-install[1]. 
As a whole the OS feels very different.  There is a lot to like about 
this new release, and a lot that is very very different.  Whatever your 
plans, I strongly recommend reading the Upstream Release Notes (a link 
is present within the SL notes)[2].  I would encourage a review of the 
SL release notes

We are still planning a customization framework for local contexts - 
like Sites and Spins from SL5 and SL6 with less overhead, but that work 
is still pending.  An easy customization framework may be useful for 
Kapteyn.

I hope this information is helpful,

Pat
