to do this we must replace derivations with attrsets in make-options-doc, since
xml can represent derivations differently from attrset but json cannot. this
also given asciidoc and mddoc the ability to handle derivation differently,
which they previously didn't have.
use the json file derivation we already have to also generate the asciidoc and
md options docs instead of formatting the options in nix. docbook docs are
already produced in derivations.
the new script produce the exact same output as the old in-nix generation.
When displaying the amount of time some step took, with no other
context, it becomes nigh impossible (especially in longer tests) to see
when specific steps finished.
The flag -cpu max leaves QEMU 6.1.0 stuck on some systems,
for example when /dev/kvm is not read-writable.
This does not happen with -cpu qemu64.
Getting stuck like that is a regression in 6.1.0 not yet present in 6.0.0
and should be fixed with 6.2.0 according to early testing with rc1.
We should consider reverting this change when we merge QEMU 6.2.0.
See #146526.

By using the new extendModules function to produce the specialisations,
we avoid reimplementing the eval-config.nix logic in reverse and fix
cross compilation support for specialisations in the process.
This reverts commit e2bea4427b.
While this commit was probably fine, I want to be conservative
with changes right before the release branch-off.
So far the extendModules commits have been adding and refactoring
expressions that did not affect derivation hashes, whereas this
commit changes the module ordering. I will open a separate PR for
it.
The involved test was nixosTests.nextcloud.basic21.
It has a testScript that is strict in nodes.nextcloud.config.system.build.vm,
in assertions about imagemagick being in the system closure.
The recursion was introduced in 329a4461a7 from
https://github.com/NixOS/nixpkgs/pull/140792
Make sure the all derivations referenced by the test script are
available on the nodes. Accessing these derivations works just fine
without this change when using 9p to mount the host's store, but when
an image is built (virtualisation.buildRootImage), the dependencies
need to be copied to the image. We don't want to copy the script
itself, though, since that would trigger unnecessary image rebuilds.
Add a copyChannel argument which controls whether the current source
tree will be made available as a nix channel in the image or
not. Previously, it always was. Making it available is useful for
interactive use of nix utils, but changes the hash of the image when
the sources are updated.
The current implementation just forks off a thread to read
QEMU's stdout and lets it exist forever. This, however,
makes the interpreter shutdown racy, as the thread could
still be running and writing out buffered stdout when the
main thread exits (and since it's using the low level API,
the worker thread does not get cleaned up by the atexit hooks
installed by `threading`, either). So, instead of doing that,
let's create a real `threading.Thread` object, and also
explicitly `join` it along with the other stuff when cleaning up.
