Hey Ron, Looks like you didn't check in the implementation of execac.
Happy February :) Cody On 07/02/2025 01:39, ron minnich wrote:
and for the last thing for the day: 1. mwait usage is back in 2. original nix bug from 2011 fixed (see commits) 3. execac command from nix is added back ok, somebody, give it a whirl.

Done that's the first attempt to call an icc in quite a while. one weird thing: either qemu does not implement mwait (unlikely) or we're not enabling it (likely) I'll see.

It panics in acmmuswitch So there's something for someone to chew on. I've been able to ditch a bit of NIX infra that is done better in 9front.
