# when a `nixos-rebuild` fails after a nixpkgs update:
# - take the failed package
# - search it here: <https://hydra.nixos.org/search?query=pkgname>
# - if it's broken by that upstream builder, then pin it: somebody will come along and fix the package.
# - otherwise, search github issues/PRs for knowledge of it before pinning.
# - if nobody's said anything about it yet, probably want to root cause it or hold off on updating.
