Hi Steve,
It makes sense to keep separate configurations (per VO) only if a site is not willing to support all VOs (part of the gridpp.ac.uk CVMFS domain). Whilst there are few VOs without presence (yet) in the UK but with stratum-0 repos located at RAL (and part of the gridpp.ac.uk CVMFS domain), there is no extra load at CVMFS client level (worker nodes), i.e. if there are no such VO jobs, the cache will not be populated with data from that specific repository.
So the recommendation is to enable the domain gridpp.ac.uk and simplify the configuration at WN level (see https://www.gridpp.ac.uk/wiki/RALnonLHCCVMFS).
@org@ is a placeholder for the repo 'shortname'.
Regards,
Catalin
