2. Systems “Go” Validation argued and agreed last week Tools work
Devil in details:
Reconfiguration: new product to hold current versions of checkrel, etc for all new releases
No details yet for selecting farm OS
CafGui doesn’t work
Drop?
Make part of a package to be picked up by all new releases? (Kick can down the road a week or three)
Can we announce tomorrow?

4. Non-release CDF software
Lots of things not in a standard release that give grief in SL5
Neurobayes (commercial)
JointPhysics
Non-SRT makefiles
User code
Will be residual support issues for a while

6. Proposed Priorities Finish new releases for SL5
Development needs to compile
Get official statement on lifetime for analysis support.
Unofficial is 10 years, but data access costs money. We have obligation to provide…
Set up a test bed with a stricter compiler; estimate project to make code compliant
Team looks at patch differences between MC, production, and Stntuple; estimate project size

10. The future OS migration End of 2011+10(??) years = end of 2021(??)
What is official lifetime?
Will we still have SL5 farms? If Yes, we’re done here
If No we’ve got some more work, and should do it before we lose experts
Maintenance
Bug fixes, help installing, odd glitches, explaining that we don’t support installation on Macintosh, etc
Joint Terminal Release
Xrootd+large file support ease data-handling effort
Reduce patch maintenance and expertise required
But will anybody use it?
