The project started around 2007/2008 and produced a virtual machine image to run LHC experiment applications in the cloud. In order to keep image sizes manageable, we looked into network file systems that could distribute the application software (including AFS/Conda, HTTP-FUSE [1], Igor-FS [2], GROW-FS [3]). None of them ticked all the boxes, so we developed CernVM-FS (CVMFS), which then developed a life beyond CernVM.
By the way, is the AFS from HLT TDAQ still used anywhere?
