I tried something similar to that and it didn't work. My guess is it's 
to do with the actual mount point? (I also tried without sudo at first, 
and when I didn't work, I tried it with sudo. I hear that's how to 
decide whether you need it or not ;) )

In any case, it only applies to the Azure Pipelines build definition, so 
there aren't any other platforms where it'll be used.
