In 99% of the cases, yes, but users are free to be more creative.

I agree that these kinds of problems are annoying to debug.  It would be
nice to offer a "debug mode" where the user can see what's going on
within the sandbox.  Maybe we could do that by opening an interactive
shell with a message saying "this is the command that we want to run"
and then let the user run that command?
