This migrates the syntax for a few configuration values,
which now need to be quoted strings for user values.
This also disables the use of a public resolver,
which is not accessible in the sandbox.
This fixes build failures with the wayland dependency:
Quoting @nevivurn:
"guestadditions->...->wayland, but the test config pulls in
modules/profiles/minimal.nix which disables xlibs and thus it won't build"

Upstream (accidentally) broke support for postgresql 12 and 13 on
v0.2.1 by changing the signature of the `from_datum` function[^1].
This went unnoticed since the release branch `0.2` did not have CI.
Furthermore, they are removing support for these versions of postgresql
on v0.3.0[^2].

Our more thorough parametrised tests uncovered that with the changes for
supporting DynamicUser, we now have the situation that for static users
the root directory within the confined environment is now writable for
the user in question.
This is obviously not what we want and I'd consider that a regression.
However while discussing this with @ju1m and my suggestion being to
set TemporaryFileSystem to "/" (as we had previously), they had an even
better idea[1]:

> * TemporaryFileSystem=/ gives us that through the ownership of / by

> * ProtectSystem=strict gives us that by mounting / read-only (while

>
> To avoid the incompatibilities of TemporaryFileSystem=/ mentioned

I like the solution with ReadOnlyPaths even more because it further
reduces the attack surface if the user is root. In chroot-only mode this
is especially useful, since if there are no other bind-mounted paths
involved in the unit configuration, the whole file system within the
confined environment is read-only.

This is to make sure that we test all of the DynamicUser/User/Group and
PrivateTmp options in a uniform way. The reason why we need to do this
is because we recently introduced support for the DynamicUser option and
since there are some corner cases where we might end up with more
elevated privileges (eg. writable directories in some cases), we want to
make sure that the environment is as restrictive as with a static
User/Group assignment.
I also removed various checks that try to os.chown(), since with our new
recursive checker those are redundant.

So far the architecture for the tests was that we would use a systemd
socket unit using the Accept option to start a small shell process where
we can pipe commands into by connecting to the socket created by the
socket unit.
This is unnecessary since we can directly use the code snippets from the
individual subtests and systemd will take care of checking the return
code in case we get any assertions[^1].
Another advantage of this is that tests now run in parallel, so we can
do rather expensive things such as looking in /nix to see whether
anything is writable.
The new assert_permissions() function is the main driver behind this and
allows for a more fine-grained way to check whether we got the right
permissions whilst also ignoring irrelevant things such as read-only
empty directories.
Our previous approach also just did a read-only check, which might be
fine in full-apivfs mode where the attack surface already is large, but
in chroot-only mode we really want to make sure nothing is every
writable.
A downside of the new approach is that currently the unit names are
numbered via lib.imap1, which makes it annoying to track its definition.
[^1]: Speaking of assertions, I wrapped the code to be run with pytest's
assertion rewriting, so that we get more useful AssertionErrors.

When experimenting on ways how to refactor the test, I wrote a
significant enough amount of Python to warrant a dedicated Python file.
This commit is mainly to prepare for that and make it easier to track
renames.

The reason why I originally used the "description" attribute was that it
can be easily used to parametrise the tests so that we can specify
common constraints and apply it across a number of different
configurations.
When porting the tests to Python, the description attribute was replaced
by inlining it into the Python code, most probably because it was easier
to do in bulk since using Nix to generate the subtest parts would be
very complicated to do since we also had to please Black (a Python code
formatter that we no longer use in test scripts).
Since we now also want to support DynamicUser in systemd-confinement,
the need to parametrise the tests became apparent again because it's now
easier to refactor our subtests to run both with *and* without
DynamicUser set to true.

Eelco has made several early contributions to NixOS including writing
the samba module among other things, but is more or less inactive these
days.
By my brief inspection, he has not committed to the nixos/ tree since
releasing Nix 2.13 in early 2023 and merging a PR to networking tests
slightly before that. A lot of these tests/modules are actually
unmaintained in practice, so we should update the code to reflect the
practical reality so someone can consider picking them up.
Depending on the startup order of the two machines it might take a few
moments to get both zones transfered, which can lead to SERVFAIL
responses on busy machines.
`nixosTests.misc` is an interesting smoketest as a last (cheap) line of
defense against Nix regressions.
We rework it to accept any arbitrary package manager for Lix.

The kernel used on aarch64-linux is built with CONFIG_BLK_DEV_LOOP=y,
so the test previously did not work on aarch64-linux.
The module for Hybla congestion control is available as a loadable
module both on x86_64-linux and aarch64-linux.
This adds an implementation of switch-to-configuration that allows for
closer interaction with the lifecycle of systemd units by using DBus
APIs directly instead of using systemctl. It is disabled by default, but
can be enabled by specifying `{ system.switch = { enable = false; enableNg = true; }; }`.
The change introduced in #308303 refers to the virtualHosts attrset
key which can be any string. The servername is the actual primary
hostname used for the certificate.
This fixes use cases like:
services.nginx.virualHosts.foobar.serverName = "my.fqdn.org";
This is a feature supported out of the box by upstream and allows the
incusd service to be restarted without impacting running
instances. While this does give up a bit of reproducibility, qemu and
lxc for example, there are clear benefits in allowing the host to
apply updates without impacting instances.

This will now be the default.
In accordance to the upstream release cycle, we now provide 2 flavours
of the percona mysql ecosystem. The default is the LTS variant,
additionally there is now the floating `percona-server_innovation`
always pointing to the most recent regular release.
- mentioned in release notes
- adapted all depending tests and tools (xtrabackup)
This release belongs to the "innovation" release track of Percona,
making it likely to diverge over time from the LTS release. Hence I just
created a separate packaging expression for this.

Added updatescript, and removed Cargo.lock as no more git deps.
New release process documented here:
a67d1f5160/book/src/support.md
Re-ordered test and removed anonymous login as logout no longer works:
[info]: Ignoring request to logout session - these sessions are not recorded
Notes:
- barf went into contrib/ and officially unsupported.
- verify was removed entirely.
- the makefile is a bit smarter now and doesn't require many
of the previous workarounds.
