I use the `rustup` package instead of the `rust` package to manage a local installation of rust. This graph seems to show installations of the `rust` package, but I don't think that accounts for `rustup`. `rustup` is recommended on Rus

Been using Linode since 2019. Service worked as expected (worked well), and I hope that won't change after this. If I had to move, I'd have to go through the pain of setting up my website(s) again, but at least I have backups, so
