<matthewbauer> have we ever considered just marking all builds that fail on hydra as broken? maybe i could write a script to do that
<matthewbauer> it just hit me that our machines are constantly building lots of things that are inevitably going to fail
<matthewbauer> hydra hits a failing job floor of like 2000 on nixpkgs-unstable, maybe just mark all of those as broken?
<matthewbauer> probably saves some money?
<samueldr> matthewbauer: it'd have to be failing for a while and consistently
<samueldr> and would hamper efforts with ZHF, but maybe something could be done to try those outside of the usual builds?
<matthewbauer> perhaps, though i would prefer us to get a real fix for those transient failures
<matthewbauer> here are the ones i was thinking of marking: https://hydra.nixos.org/eval/1523920#tabs-still-fail
<matthewbauer> some false positives exist there though i'm sure
<samueldr> only those Failed, so not timeouts and not dependency failed
<samueldr> hmm, and some would be more suited to have their platforms be reduced I guess

<aristid> so
<aristid> ever since alsa lib was updated from 1.1.8 to 1.1.9, pulseaudio does not detect UCM anymore
<aristid> and pulseaudio's alsa module is broken with linker errors (at runtime, yay .SO files) if UCM is not available
<aristid> let me add it to the PA patches
<aristid> what's the recommended way to fetch a patch from upstream these days?
<andi-> just add .patch to the above urland use fetchpatch
<aristid> andi-: yeah, i'll use the main git repo, not github but yeah

<aristid> i wish all hydra agents were as fast as the epyc server :D
<dhess> aristid: what are its specs?
<aristid> dhess: no idea
<aristid> dhess: i just know the firefox build is a lot faster on it than on one of the old TU Delft servers! :-)
<dhess> samueldr: thanks. I'm about to provision an x86_64-linux builder.
<dhess> aristid: :)
<samueldr> there's a nixos user shilling^W ensuring good support for NixOS on packet.net 'round here :)
<aristid> samueldr: "just $1 per hour" uh
<dhess> I know that Packet.net is really nice to the Nix project, but damn, their hardware is expensive.
<aristid> dhess: i guess you get better quality & service than from hetzner or so, but the price difference is ... real :D
<samueldr> I was also saying that since NixOS is supported
<samueldr> while generally not an issue otherwise, supported out of the box is nice
<dhess> aristid: yeah Hetzner is exactly what I always compare it to. Granted, Hetzner is about 20 minutes of hassle at the start to run clever's kexec or whatever, but after that, it just works.
<aristid> dhess: you don't need kexec for their physical boxes, at least
<aristid> dhess: are you referring to their VMs?
<dhess> aristid: really? Do they have a NixOS boot image now?
<dhess> No, I mean their dedicated hosts.
<aristid> dhess: no you can boot into one of their recovery linux images and then just use the nixos installer
<aristid> dhess: or nixops can also do it automatically for you
<aristid> granted it's been a while since i did that
<dhess> aristid: oh. I actually prefer to use kexec to boot the NixOS installer image.
<dhess> It would be nice if they booted into the NixOS installer image directly. I was hoping you meant that. :)
<aristid> dhess: i think i just chrooted to use the nixos installer
<aristid> dhess: why is that worse than kexec?
<dhess> I wouldn't say it's "worse." But with kexec, I can basically pre-configure it precisely for the hardware on which it's being installed.
<aristid> dhess: where can i find the documentation for this "kexec method"? :)
<dhess> as mentioned there, one advantage is that you can have ZFS support out of the box. Want to install NixOS on a zfs root? Done.

<emily> I wish the "kexec method" was more than a subdirectory of .nix files you have to manually patch up to use...
