I find that surprising given that Debian breaks Rust programs up into individual apt packages, but ultimately, other distros do not have this issue. It’s also about userspace programs and not the kernel, which does not use external packages and so sidesteps this completely.
Debian forky has Rust in the kernel on by default.
Right, from my understanding, Debian was packaging Rust programs in the same way as C ones. So they’d update the individual library and it should be all good. They deduplicated all of the dependencies in their trees.
This seems reasonable to me. If you have a tarmaggeedon, you update one library instead of thousand of packages. Although I am not sure how well this can work in Rust with monomorphization.
