I’m working with LSST folks in Southampton who have code that is updated quite regularly. A while ago, I tested to see whether git could clone at time of execution (I cannot remember which site this was at), and it was a success. However, RAL does not have git installed, as similar code fails at that site. I’ve asked this before and didn’t really get a full answer. Is there any way of knowing which sites have which software installed? It would save new users a lot of pain when trying to get up and running, or even just testing. 

Cheers
