This might be too late for the relase but something that has bothered me for a while is that nixops - a major tool in the nix ecosystem - is not overridable. I had tried there https://github.com/NixOS/nixpkgs/pull/41472 but the doc system eludes me so if any nixops maintainer feels like it please go ahead.
I did an update on openmpi a while ago. I would be great if we could merge that before the feature freeze. From my side this PR is basically ready to be merged but the update affects quite a number of packages. Community feedback would thus be appreciated. https://github.com/NixOS/nixpkgs/pull/54877
Please have mercy on my nixos-rebuild times and enable BLK_SED_OPAL in the kernel. Without it, computers with self-encrypting drives (like my ThinkPad) can’t resume from suspend when encryption is enabled.
That kernel option is enabled by default in Fedora, Debian, etc.
Sorry for the delay, folks! The branch-off took place as planned last week; the ZHF issue now also exists, any contributions to fixing broken stuff welcome!
