(Agreed.  Let's collect a few more items that need clarification and
then edit the description.)

What requests do users make to download the Linux sandbox thing, and how

For comparison, here are the patterns we're currently using:

I'm afraid that adding another data source than our webstats is out of
scope for the moment.  It's certainly interesting for the future, and we
