Hello,
Current CVMFS pages I can find on the wiki:
* https://www.gridpp.ac.uk/wiki/RAL_Tier1_CVMFS - general - does this
need updating?
* https://www.gridpp.ac.uk/wiki/UK_CVMFS_Deployment - looks pretty
comprehensive, worth a look
* https://www.gridpp.ac.uk/wiki/CVMFS_Use_Cases_for_GridPP - evolving,
everyone please feel free to contribute
* https://www.gridpp.ac.uk/wiki/A_quick_guide_to_CVMFS - I think I
need to update this with the gsi instructions and test commands
(currently has the web interface instructions which I think is being
deprecated).
Thanks again everyone, Tom
