The `nix.*` options, apart from options for setting up the
daemon itself, currently provide a lot of setting mappings
for the Nix daemon configuration. The scope of the mapping yields
convience, but the line where an option is considered essential
is blurry. For instance, the `extra-sandbox-paths` mapping is
provided without its primary consumer, and the corresponding
`sandbox-paths` option is also not mapped.
The current system increases the maintenance burden as maintainers have to
closely follow upstream changes. In this case, there are two state versions
of Nix which have to be maintained collectively, with different options
avaliable.
This commit aims to following the standard outlined in RFC 42[1] to
implement a structural setting pattern. The Nix configuration is encoded
at its core as key-value pairs which maps nicely to attribute sets, making
it feasible to express in the Nix language itself. Some existing options are
kept such as `buildMachines` and `registry` which present a simplified interface
to managing the respective settings. The interface is exposed as `nix.settings`.
Legacy configurations are mapped to their corresponding options under `nix.settings`
for backwards compatibility.
Various options settings in other nixos modules and relevant tests have been
updated to use structural setting for consistency.
The generation and validation of the configration file has been modified to
use `writeTextFile` instead of `runCommand` for clarity. Note that validation
is now mandatory as strict checking of options has been pushed down to the
derivation level due to freeformType consuming unmatched options. Furthermore,
validation can not occur when cross-compiling due to current limitations.
A new option `publicHostKey` was added to the `buildMachines`
submodule corresponding to the base64 encoded public host key settings
exposed in the builder syntax. The build machine generation was subsequently
rewritten to use `concatStringsSep` for better performance by grouping
concatenations.

It looks like "make-bcache" also registers the devices, so the separate
registration afterwords is unnecessary.
Previously, the separate registration right afterwords didn't cause
a problem, presumably because it won the race with make-bcache's
registration. After 1640359f33 slightly
changed the timing of command execution in tests, the separate
registration often fails with the error message "device already
registered", stopping the test.
Currently, the installer tests just hang after the initial install phase
on i686 because qemu just quits because of the gic parameter.
Fix this by doing x86 things for both x86-64 and i686.
We apparently didn't fit anymore. I don't think this test is meant
to (also) check closure size.
Note: as of this commit, the test is blocked by a fontconfig problem,
so I tested with that merge temporarily reverted.
The cyclic dependency of systemd → cryptsetup → lvm2 → udev=systemd
needs to be broken somewhere. The previous strategy of building
cryptsetup with an lvm2 built without udev (#66856) caused the
installer.luksroot test to fail. Instead, build lvm2 with a udev built
without cryptsetup.
Fixes#96479.

This appears to avoid requiring KVM when it’s not available. This is
what I originally though -cpu host did. Unfortunately not much
documentation available from the QEMU side on this, but this appears
to square with help:
$ qemu-system-x86 -cpu help
...
x86 host KVM processor with all supported host features
x86 max Enables all features supported by the accelerator in the current host
...
Whether we actually want to support this not clear, since this only
happens when your CPU doesn’t have full KVM support. Some Nix builders
are lying about kvm support though. Things aren’t too slow without it
though.

Also, add some sleep statements in between, which seems to at least feel
like it causes
> WARNING: Device /dev/vda* not initialized in udev database even after waiting 10000000 microseconds.
To occur less frequently.
This eventually still succeeds after some amount of waiting, I suspect
some racyness in the way lvm's udev-triggered scripts trigger other
units.
- Create a child configuration named "Work" with an extra config file.
- Name the default configuration as "Home" :-)
- Once the VM is setup, reboot and verify that it has booted into
default configuration.
- Reboot into the "Work" configuration via grub.
- Verify that we have booted into the "Work" configuration and that
the extra config file is present.
This test works for the simple grub configuration and simple UEFI
Grub configuration. UEFI Systemd is not included in the test.
He prefers to contribute to his own nixpkgs fork triton.
Since he is still marked as maintainer in many packages
this leaves the wrong impression he still maintains those.
previously one of the tests would fail with

Shortening the test name fixes the issue.
Since 1b11fdd0df the test VM
depends on some extra packages to build the system to be installed.
This broke the installer test as it tried to download/build these
packages in a sandbox.
The wallpaper used is *structurally compatible* with the other one,
meaning that the logo is at the same location, and not bigger.
It has one drawback: the logo is brighter, which clashes with the grub
usage. This is to be fixed with new options in grub.
Since a9d69a74d6, the passphrase prompt
now no longer starts with "Enter passphrase for" but now it's just
"Passphrase for", which causes the luksroot installer test to fail.
I've tested this on a x86_64-linux machine and the test now succeeds.

This makes the command ‘nix-env -qa -f. --arg config '{skipAliases =

- qtikz: use libsForQt5.callPackage
This ensures we get the right poppler.

diffpdf: fixup
In commit 17dd7bcd89 the systemd unit
generator now uses lndir instead of "ln -s", so we need to have lndir
available in the Nix store for the installer tests to be able to build
the units and thus the whole system.
This should fix the installer tests, although I have only tested it with
the "simple" subtest.

-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".
The installer tests are failing after 505e94256e
due to `nixos-rebuild switch` in the installed system trying to build
stdenvNoCC.
Seems that previously, stdenvNoCC wasn't in the installed
system either, but all the direct dependencies for the build were
(I don't really understand why, for that matter), so the building
actually went fine and everything worked.
But now gcc is also a direct build dependency due to allowedRequisites
containing gcc (even though it doesn't become a runtime dependency)
which doesn't get to the installed system.
All in all, let's ensure stdenvNoCC actually gets to the installed
system. It's after all necessary in almost any NixOS config build.
Restructure the nixos-artwork to make it easy to selectively
incorporate other components from upstream without needing to download
the full package.
Until now only the Gnome_Dark wallpaper was included. Add other
wallpapers available in the package repository.
OVMF{,CODE,VARS}.fd are now available in a dedicated fd output, greatly
reducing the closure in the common case where only those files are used (a
few MBs versus several hundred MBs for the full OVMF).
Note: it's unclear why `dontPatchELF` is now necessary for the build to
pass (on my end, at any rate) but it doesn't make much sense to run this
fixup anyway,
Note: my reading of xen's INSTALL suggests that --with-system-ovmf should
point directly to the OVMF binary. As such, the previous invocation was
incorrect (it pointed to the root of the OVMF tree). In any case, I have
only built xen with `--with-system-ovmf`, I have not tested it.

Closes https://github.com/NixOS/nixpkgs/pull/25855
The key distinction I'm drawing is that there's a component that deals
with the store of the machine being built, and another component for
the store building it. The inner part of it assumes nothing from the
builder (doesn't need chroot or root powers) so it can run comfortably
inside a Nix build, as well as nixos-rebuild. I have some upcoming work
that will use that to significantly speed up and streamline image builds
for NixOS, especially on virtualized hosts like EC2, but it's also a
reasonable speedup on native hosts.
