That said, going up a directory would seem to imply that dstat could easily be loading completely arbitrary code from a directory it has no exclusive claim to and thus cannot meaningfully trust. Indeed, as I understand `share/` that is exactly the point. This really doesn't strike me as being a safe thing to do, and I can readily see why the author would reject it on security grounds. This seems to me to be a distinction with little meaningful difference, though I can see where some people might disagree.
As I tell PMs, designers, and engineers I work with far too often for my own comfort, someone else's poor security decisions are no excuse for our own.
