I made a subtle change at the last minute with the previous PR to use `*` for the glob instead of `.`, because the tmpdir had a `.tmp` file I didn't want. But - this caused us to miss the `.cargo` directory which has the config file. And while I'd been testing builds with no network, of course cargo was really pulling content from `~/.cargo`. When I went to do a scratch build in Koji, that failed obviously. I tested this makes things [work with a SRPM scratch](https://koji.fedoraproject.org/koji/taskinfo?taskID=27490830) and in my dev container under `bwrap --unshare-net` with `mv ~/.cargo{,.orig}`.
