exportReferencesGraph is deprecated and doesn't have the generated
initial Nix database contain the SHA256 of the contents of the store
paths, which breaks various things under Nix 2.0.
- `localSystem` is added, it strictly supercedes system
- `crossSystem`'s description mentions `localSystem` (and vice versa).
- No more weird special casing I don't even understand

Instead of imagemagick built with many libraries
(notably librsvg which these days requires rust)
use imagemagick_light with support for libtiff added.
These (outdated) derivations are only used by nixos/lib/testing.nix.
If we want to provide jquery & jquery-ui packages this is better done
in nodePackages.
Among other things, this will allow *2nix tools to output plain data
while still being composable with the traditional
callPackage/.override interfaces.
- Add a new parameter `imageType` that can specify either "efi" or
"legacy" (the default which should see no change in behaviour by
this patch).
- EFI images get a GPT partition table (instead of msdos) with a
mandatory ESP partition (so we add an assert that `partitioned`
is true).
- Use the partx tool from util-linux to determine exact start + size
of the root partition. This is required because GPT stores a secondary
partition table at the end of the disk, so we can't just have
mkfs.ext4 create the filesystem until the end of the disk.
- (Unrelated to any EFI changes) Since we're depending on the
`-E offset=X` option to mkfs which is only supported by e2fsprogs,
disallow any attempts of creating partitioned disk images where
the root filesystem is not ext4.
It is quite complicated to test services using the test-driver when
declaring user services with `systemd.user.services` such as many
X11-based services like `xautolock.service`.
This change adds an optional `$user` parameter to each systemd-related
function in the test-driver and runs `systemctl --user` commands using
`su -l $user -c ...` and sets the `XDG_RUNTIME_DIR` variable
accordingly and a new function named `systemctl` which is able to run a
systemd command with or without a specified user.
The change can be confirmed with a simple VM declaration like this:
```
import ./nixos/tests/make-test.nix ({ pkgs, lib }:
with lib;
{
name = "systemd-user-test";
nodes.machine = {
imports = [ ./nixos/tests/common/user-account.nix ];
services.xserver.enable = true;
services.xserver.displayManager.auto.enable = true;
services.xserver.displayManager.auto.user = "bob";
services.xserver.xautolock.enable = true;
};
testScript = ''
$machine->start;
$machine->waitForX;
$machine->waitForUnit("xautolock.service", "bob");
$machine->stopJob("xautolock.service", "bob");
$machine->startJob("xautolock.service", "bob");
$machine->systemctl("list-jobs --no-pager", "bob");
$machine->systemctl("show 'xautolock.service' --no-pager", "bob");
'';
})
```
Fakeroot seems to always give the owner write bit to any files touched
inside it (presumably to easily simulate the fact that root can still
modify such files). So do an explicit chmod to remove them.
This should finally solve #32242 after the EC2 images are regenerated
with this change.
https://hydra.nixos.org/build/66143116
This fixes #28768 because during an image build, Nix sees bad store
timestamps and attempts to fix them, but can't fix them on a running
system (due to being inside a builder). Since timestamps on the store
are supposed to be 1 anyway, if we fix this, that fixes image building
inside booted images made this way.
Note that this adds quite a bit of noise to the output, because running
`cptofs` under `faketime` causes a bunch of seemingly spurious error
messages and my attempts to suppress them all failed. We'll fix it when
`cptofs` gets a native timestamp preservation feature.
-s, --script: never prompts for user intervention
Sometimes the NixOS installer tests fail when they invoke parted, e.g.
https://hydra.nixos.org/build/62513826/nixlog/1. But instead of exiting
right there, the tests hang until the Nix builder times out (and kills
the build). With this change the tests would instead fail immediately,
which is preferred.
While at it, use "parted --script" treewide, so nobody gets build
timeout due to parted error (or misuse). (Only nixos/ use it, and only
non-interactive.)
A few instances already use the short option "-s", convert them to long
option "--short".
Regression introduced by a02bb00156.
The fix is done by disabling writableStore, because the latter will set
up an overlayfs on the Nix store within the VM, which in turn will
discard all the outputs of the resulting output path.
However in runInMachine we actually *want* the contents of the generated
path and also don't want a writable store within the VM (except of
course for $out, which is writable anyway).
I've added a small regression test to verifify the output in
nixos/tests/run-in-machine.nix to make sure this won't break again in
the future.
