@raitobezarius:matrix.orgraitobezariusI learn that bindgen cannot generate all macro constants because of https://github.com/rust-lang/rust-bindgen/issues/75301:52:10

@aenderboy:matrix.orgaenderboy sorry for the blasphemous question, but: Is there a cloud-init-like impurity sidechannel for nixos? I dont want to build 800 qemu images with nixos generators. 19:09:16
@aenderboy:matrix.orgaenderboyspecifically i want to set hostname and network config with it. Can maybe config.services.cloud-init do that?19:12:17
@raitobezarius:matrix.orgraitobezarius #nixops:nixos.org is fine for that 22:40:51
@raitobezarius:matrix.orgraitobezariusalso you may want to use nix-serve-netboot if you are going to deploy those images via a iPXE server maybe22:41:39
@raitobezarius:matrix.orgraitobezariusdepends your way of doing things22:41:43
@raitobezarius:matrix.orgraitobezariusI think also that the hostname/netconf via cloud-init on NixOS is semi broken because no one really maintain it and care about that sort of stuff22:42:07
@raitobezarius:matrix.orgraitobezariusI'd really implement this sort of auto-configuration as an 2-step initialization22:42:28
@raitobezarius:matrix.orgraitobezarius(1) Step 1: produce a generic configuration capable of running cloud-init to fetch the final nixos-configuration22:42:43
@raitobezarius:matrix.orgraitobezarius(2) Step 2: trigger a rebuild switch22:42:48
@raitobezarius:matrix.orgraitobezariusUsing truly cloud-init with their APIs is a mistake which will cause hard-to-debug issues IME22:43:04

i'm using cloud init now for some small things and i already think i would have been better off rewriting that thing myself.

@raitobezarius:matrix.orgraitobezariusYeah, that's the classical story18:17:51

@woobilicious:matrix.orgwoobilicious I put config.boot.kernelPackages.perf in my nixos systemPackages...and it's segfaulting on my bcachefs testing kernel..anyone seen this before? 03:10:33
@woobilicious:matrix.orgwoobiliciousohh...packagesFor is probably for a different kernel version?hmm03:13:36
@woobilicious:matrix.orgwoobiliciouswhat is weird is I have an old version in pinned nixpkgs and it works.03:15:14
@raitobezarius:matrix.orgraitobezarius perf is running well on my side on unstable-small 03:16:34
@woobilicious:matrix.orgwoobiliciouspulling in linux_testing.perf seems to build from source..not a good sign.03:17:21
@raitobezarius:matrix.orgraitobezariusindeed03:17:29
@woobilicious:matrix.orgwoobiliciousokay...6_6 and 6_7 segfault as well....hmm03:19:39
@woobilicious:matrix.orgwoobiliciousofc gdb doesn't like that perf is wrapped in a bash script lol03:21:52
@woobilicious:matrix.orgwoobiliciousokay it's failing in clone3 hmmno clue where to start debugging this lol03:30:41
