Gloria

  • For the to-do list: we need to solve the issue of the copy of Geant4 sources

Hubert

  • LbScript v6r2 put in production and immediately overridden by v6r2p1 because of a bug in the CVMFS-specific optimization in SetupProject

Marco Ca.: we do not have proper certification of LbScript releases.
For AFS we have a pool of guinea pigs, but we do not have the dev/prod mechanism on CVMFS and we are not testing on the grid.

Hubert: the dev/prod mechanism is possible for CVMFS, but was never used.

Joel: we should use the certification system for the validation.

  • Changed the root paths for CERNVM from /opt to /cvmfs. It should be transparent to the users (may be a reboot needed).
  • Modified the post-login script on CERNVM to make X509 environment variables pointing to the /cvmfs/grid.cern.ch directory (at Tier-1s we use what's provided or fall back to CVMFS if nothing available).
  • Plans to use the LCG externals from the SFT CVMFS repository.
    (...discussion...) That will make the CVMFS installation at Tier-1s more unreliable, so we decided to stick to the current scheme.
