Timeline 1

July 2003: decision: certify Red Hat 10 beta, goal: November
Sept 2003: RH strategy change (Fedora/Enterprise)
Oct 2003:
- LXCERT: continue with 10beta=Fedora
- LXCERT: on hold
- HEPiX: negotiate wih RH
Feb 2004: negotiations stopped, CEL3
Mar 2004: LXCERT meeting, “real” certification starts

May 2004: LXCERT meeting (still no end date, “experiments need 1 month after full Application Area SW is available”, summer period worries)
June 2004: CEL3 -> SLC3, no real impact on certification
July 2004: LXCERT meeting (still no fixed end date, “end of September” target)
July 2004: LXPLUS test nodes available
Aug->October: POOL issue
- Summer period: (some) production managers not available
Nov 1st 2004: SLC3 certified
Jan 17th 2005: LXPLUS migrated

[non-issue]: Looong delay (negotiations) before real start (6months) – but: allowed OS to settle
Summer period: absences, conflict with DataChallenges, beam time. Avoid? (unrealistic for roll-out in autumn)
POOL issue took too long to emerge+address, was blocking whole production chain: need to 'certify around' identified issues
[non-issue]: LXPLUS migration: delayed by HW unavailability
[non-issue]: non-LHC not reacting (their problem, but influences 7.3 phase-out timeline)
