Notes:

Steve Timm - Have you tried to pass a user token to the job?
Marco Mam - You can pass a user token to a job at submission time, outside of the infrastructure.
David Dykstra - Is there renewal for these tokens?
Marco Mam - Condor does not support it yet.

Edgar - How will the job know which authentication method to use GSI vs Tokens?
Marco Mam - You have to specify for the CE on the factory.
jdost - Do we have to have two entries for a factory if we want to support both methods?
Marco Mam - Yes

jdost - Is 3.7 ready for production environments?
Marco Mam - 3.7.1 is ready.

Brian Lin - When is Autoconf going to be available?
Marco Mas - As soon as possible. Probably November

Tanya - How is Namratha’s work related to Dave Dykstra’s work?
Marco Mam - For now her approach is only using Fuse. We’ll look into using cvmfsexec in the future
Edgar - Asked for more details on the implementation.
Marco Mam - Depending on the OS the feature will look find the best way to make cvmfs available automatic.
Dave Dykstra - Is it using cvmfs exec now?
Marco Mam - Not yet. It’s a bit more difficult to implement this feature with cvmfsexec, but we’ll use it in the future.
Marco Mam - This feature comes on the next release as a factory script.

jdost - The OSG schedule for 3.7 is ITB this week and production the week of the 21.
Marco Mam - This is positive, the earlier we can reduce the number of versions the better

Edgar - We are up to be early adopters of the Python 3 version

Dave Dykstra - When you have RHEL 7.8 with unprivileged users cvmfsexec will be able to clean the mount points even after a kill -9. This specifically useful to handle preemptions.
Marco Mam - Jobs running inside a Docker container could possibly handle preemptions well.

jdost - Suggested having a dedicated meeting for the Frontend Decision Channel discussion.
Marco Mam - What would be good topics for this meeting
Edgar - Suggested: How are we going to distribute the topic, What’s the transition plan, What features are available in each version
Brian Lin - Suggested putting together an architecture diagram.
Marco Mam - Mentioned that we don’t have a final design yet, but would provide what we have now.
