I'm not sure I follow the logic of this comment... how does using Qt plugins built by nix alleviate the .so.5 vs .so.6 version issue?

Also, why use rsync instead of simply ln -s? Ideally we'd like to avoid copying files b/w outputs.

...because Nix builds Qt plugins against nixpkgs' libtiff and they end up linking to .so.6

Also, why use rsync instead of simply ln -s? Ideally we'd like to avoid copying files b/w outputs.

No good reason at all, other than I wanted a "synchronize these two directory trees recursively" operation, and rsync is one. Either way, we want to be removing all of these plugins, and for all versions of cuda, so we'll have rewritten this patch before we can close #224646
