Hi Ewan, The ATLAS images used on various cloud resources are preconfigured SL6. They don't provide the hooks needed to contextualise as LHCb does. There is some activity to look at uCernVM but at this stage running on Vac seems beyond the effort we have available. Personally I like the idea but the best we can do is make decisions to not exclude the Vac model. If you have time to look into the details then we can help. One aspect are the wrapper scripts which are being re-jigged in ATLAS now.
