Modules built in to the kernel can attempt to load firmware before
init is started. To guarantee the firmware is accessible to them
where they expect, /lib has to exist in the initramfs — it can't be
created later by init, because by that point the module may already
have tried and given up.
The virtualisation.directBoot.initrd option was added for netboot
images, but the assertion to check directBoot enabled if it was used
caused an infinite recursion if it was. Minimal reproduction:
import nixos/tests/make-test-python.nix ({ pkgs, ... }: {
name = "";
nodes = {
machine = { config, ...}: {
imports = [ nixos/modules/installer/netboot/netboot-minimal.nix ];
virtualisation.directBoot = {
enable = true;
initrd = "${config.system.build.netbootRamdisk}/${config.system.boot.loader.initrdFile}";
};
};
};
testScript = "";
}) {}
The fix is to swap the two conditions, so that cfg.directBoot.enable
is checked first, and the initrd comparision will be short circuited.
This wasn't noticed during review because in earlier versions of the
virtualisation.directBoot patch, the assertion was accidentally in the
conditional above, so wasn't evaluated unless port forwarding was in
use.
Aliases exist for a reason. Sure it is nice to make sure that
some aliases aren't used within Nixpkgs, but this creates two problems
which are far worse than your failing to meet your neatness compulsions.
- Users encounter missing attributes, https://github.com/NixOS/nixpkgs/issues/264577
wasting their time, stalling their progress, and even occupying others
time that would be better spent on fixing *real* issues.
- Hydra doesn't treat evaluation errors seriously enough, with the
effect that actual relevant test failures are masked by evaluation
failures such as those caused by this no aliases business.
- We don't even have the infrastructure to get rid of aliases, because
all warnings in package attributes are disallowed by Nixpkgs CI
tooling, last I checked.
Before re-disabling this, make sure that
- An actually helpful deprecation process is in place.
- Aliases are still allowed when `nixos-lib.runTests` and
`pkgs.testers.runNixOSTest` are invoked by external projects.
For instance, `all-tests.nix` could provide such an
override (e.g. with `newScope`).
setuptools.__version__ = '68.2.2.post0'
setup.py fails with a parse error when trying to convert 'post0' to an
int. patch the code so it only will convert the first to values returned
by split('.')
