For example, you can get that information from Debian using [1]. It appears that Fedora isn't distributing rustc at *all*, at least according to [2], so apparently for Fedora people will need to install it from source. [1] https://packages.debian.org/search?keywords=rustc&searchon=names&suite=all§ion=all [2] https://idroot.us/install-rust-fedora-37/ The other thing that would be worth documenting is (b) something about what versions of Rust people have actually tested. The comments at [3] are quite scary, since per [4], the minimum version of Rustc supported is 1.62.0 --- and per [3], **only** Rust 1.62.0 is supported, since we use unstable Rust features. [3] https://rust-for-linux.com/rust-version-policy [4] https://docs.kernel.org/process/changes.html But for example, with Debian, Debian stable is shipping Rust 1.48.0, and Debian testing (which is currently in "hard freeze" so it can be released as Debian stable this summer) is shipping Rustc 1.63.0. Since I use Debian testing, the question which is foremost in my mind is whether I can expect to have things work if I use the distro-provided 1.63.0 rustc, or is this really a case of "it's not Rust 1.62.0, so good luck to you"? If the goal is accelerate adoption of Rustc, and calm people's fears vis-a-vis using Rust, it's not enough to say, "why don't you use the distribution-provided version or Rust"? It would be helpful if those Rust pioneers can share what versions of Rust they have tested against, especially for those commonly used distributions, such as Debian, and give us a report whether we should expect things to work, so we can ignore the scary warning from the build system that we're using an unsupported version of Rust, and if it breaks, we get to keep both pieces. And for those distributions that don't currently ship Rust, such as Fedora, if someone could build their own unofficial packages, until we can convince Red Hat to start shipping -their own supported Rust compilers, that might be a great way of bridging that gap.
