config.boot.loader.grub.device is just an alias that gets assigned to config.boot.loader.grub.devices.
If config.boot.loader.grub.device is set to null, it will fail with the following error
as described in https://github.com/nix-community/nixos-generators/issues/339
This patch is about removing `wireguardPeerConfig`,
`dhcpServerStaticLeaseConfig` - a.k.a. the
AbstractSingletonProxyFactoryBean of nixpkgs - and friends.
As a former colleague said
> worst abstraction ever
I second that. I've written enough networkd config for NixOS systems so
far to have a strong dislike. In fact, these don't even make sense:
`netdevs.wireguardPeers._.wireguardPeerConfig` will be rendered into
the key `[WireGuardPeer]` and every key from `wireguardPeerConfig` is in
there. Since it's INI, there's no place where sections on the same level
as wireguardPeerConfig fit into. Hence, get rid of it all.
For the transition, using the old way is still allowed, but gives a
warning. I think we could drop this after one release.
The tests of rosenpass and systemd-networkd-dhcpserver-static-leases
were broken on the rev before, hence they were updated, but are still
not building.
We remove the global rootlog in favor of instantiating the logger as
required in the __init__.py and pass it down as a parameter (of our
AbstractLogger type).
Previously, the XML logging was always present and only created an
output file if a special environment variable was present. We now only
create the XML logger if the environment variable is present, saving us
from logging to XML internally if it is not required.
We add a new logger that allows generating a junit-xml compatible report
listing the subtests used in the nixos integration test. Junit-xml is a
widely used standard for test reports. The report can be used for quick
evaluation of which subtest failed.
We use the newly AbstractLogger class and separate the XML and Terminal
logging that is currently mixed into one class. We restore the old
behavior by introducing a CompositeLogger that takes care of logging
both to terminal and XML.
We do not use the generic "nested" function but introduce a separate
subtest log call. This will later allow us to track subtests and account
logs to specific subtests.
When passing a path to restartTriggers or reloadTriggers, X-Restart/Reload-Triggers
will get populated by the absolute path of the file on the machine where the
config is evaluated. This patch corrects this behavior.
This allows us to set things like dependencies in a way that we can
catch typos at eval time.
So instead of
```nix
systemd.services.foo.wants = [ "bar.service" ];
```
we can write
```nix
systemd.services.foo.wants = [ config.systemd.services.bar.name ];
```
which will throw an error if no such service has been defined.
Not all cases can be done like this (eg template services), but in a lot
of cases this will allow to avoid typos.
There is a matching option on the unit option
(`systemd.units."foo.service".name`) as well.
As the TODO says, this is already included by the script.
If adding a device, including this again here would result in either
two devices being added, or, if they were explicitly named, an error
due to reuse of the name.
- use normal VM nodes for target, with some extra trickery
- rename preBootCommands to postBootCommands to match its actual intent
- rename VMs to installer and target, so they're not all called machine
- set platforms on non-UEFI tests properly
- add missing packages for systemd-boot test
- fix initrd secrets leaking into the store and having wrong paths
Right now the worst case chain of events for building an ISO on Hydra is
- copy everything to squashfs builder
- run squashfs builder
- download squashfs from builder
- compress squashfs
- upload squashfs to S3
- copy squashfs to ISO builder
- run ISO builder
- download ISO from builder
- compress ISO
- upload ISO to S3
This inlines the squashfs build into the ISO build, which makes it
- copy everything to ISO builder
- run ISO builder
- download ISO from builder
- compress ISO
- upload ISO to S3
Which should reduce queue runner load by $alot per ISO, which we have four of on small channels
(one release, one test per arch) and a lot more than four of on large channels (with various desktops)

The goal here was to get the following flake to build and run on
`aarch64-darwin`:
```nix
{ inputs.nixpkgs.url = <this branch>;
outputs = { nixpkgs, ... }: {
checks.aarch64-darwin.default =
nixpkgs.legacyPackages.aarch64-darwin.nixosTest {
name = "test";
nodes.machine = { };
testScript = "";
};
};
}
```
… and after this change it does. There's no longer a need for the
user to set `nodes.*.nixpkgs.pkgs` or
`nodes.*.virtualisation.host.pkgs` as the correct values are inferred
from the host system.
systemd-boot-builder.py calls nix-env --list-generations which creates
$HOME/.nix-defexpr/channels/nixos if it doesn't exist. This would cause a folder
/homeless-shelter to show up in the final image which in turn breaks nix builds
in the target image if sandboxing is turned off (as /homeless-shelter is never
allowed to exist).
Adds a function to wait for a new QMP event with a model filter
so that you can expect specific type of events with specific payloads.
e.g. a guest-reset-induced shutdown event.
Building a python environment with python3Minimal requires hydra
to bootstrap pip and build all packages used in the environment
which would otherwise not be built. This reduces cache re-use and duplicates things.
Also common dependencies normally included in python itself
are not properly checked and can cause hard to debug errors
because everyone just assumes those modules are there.
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`).
This is a fixup for c1ae82f448.
nix' `passAsFile` does not create empty files for variables that are
`null`.
This results in the following error for units that have no overrides or
content, but are, e.g. `wantedBy`:
`mv: cannot stat '': No such file or directory`.
Minimal reproducer:
`systemd.units.empty.wantedBy = [ "multi-user.target" ];`
This is often necessary when a unit is loaded in via `systemd.packages`.
