For now there aren't many popular drivers that use Rust, but there are currently 3 in-development GPU drivers that use it, and I suspect that when those get merged that'll be the real point of no return:
I suspect the first one of those to be actually used in production will be the Tyr driver, especially since Google's part of it and they'll probably want to deploy it on Android, but for the desktop (and server!) Linux use-case, the Nova driver is likely to be the major one.
I believe Google has developed a Rust implementation of the binder driver which was recently merged, and they are apparently planning to remove the original C implementation. Considering binder is essential for Android that would be a major step too.
This is so cool! I love things like that, it feels like fresh air after years and years of anachronistic retro-vibes that seem to be a part of C-programming culture.
Arch never failed me. The only time I remember it panicked was when I naively stopped an upgrade in the middle which failed to generate initramfs but quickly fixed it by chroot'ing and running mkinitcpio. Back up in no time
Interesting, I use both (NixOS on servers, Arch for desktop) and never seen that. Seems you're referring to this: https://rust-for-linux.com/drm-panic-qr-code-generator (which looks like this: https://github.com/kdj0c/panic_report/issues/1)
Too bad NixOS and Arch is so stable I can't remember the last time any full system straight up panicked.
