mysql already has its socket path hardcoded to to
/run/mysqld/mysqld.sock.
There's not much value in making the pidDir configurable, which also
points to /run/mysqld by default.
We only seem to use `services.mysql.pidDir` in the wordpress startup
script, to wait for mysql to boot up, but we can also simply wait on the
(hardcoded) socket location too.
A much nicer way to accomplish that would be to properly describe a
dependency on mysqld.service. This however is not easily doable, due to
how the apache-httpd module was designed.
As we don't need to setup data directories from ExecStartPre= scripts
anymore, which required root, but use systemd.tmpfiles.rules instead,
everything can be run as just the mysql user.
define commands like "waiting for the mysql socket to appear" or "setup
initial databases" in a let expression, so the main control flow becomes
more readable.
We need to keep using `RuntimeDirectory=mysqld`, which translates to
`/run/mysqld`, as this is used for the location of the file socket, that
could differ with what is configured via `cfg.pidDir`.
Before, changing any peers caused the entire WireGuard interface to
be torn down and rebuilt. By configuring each peer in a separate
service we're able to only restart the affected peers.
Adding each peer individually also means individual peer
configurations can fail, but the overall interface and all other peers
will still be added.
A WireGuard peer's internal identifier is its public key. This means
it is the only reliable identifier to use for the systemd service.

$ tmux
error creating /run/user/$(id -u)/tmux-1000 (No such file or directory)
/run/user/$UID/ is created by pam_systemd(3) which also populates
XD_RUNTIME_DIR with that value.
Alternatively, TMUX_TMPDIR might simply default to XDG_RUNTIME_DIR
without providing the same directory yet again as default string in
parameter substitution, however such behaviour change is subject to
another patch.
In fact, with `security.polkit.enable = false` systemd_logind(8) fails
to start and /run/user/$UID/ is never created for unprivileged users
in proper login sessions; XDG_RUNTIME_DIR would consequently not be
set either.
Removing the fallback to /run/user/$UID/ would have caused TMUX_TMPDIR
to be empty, which in turn would lead tmux(1) to use /tmp/. This
effectively breaks the idea of isolated sockets entirely while hiding
errors from the user.
We differentiate between modules and baseModules in the
VM builder for NixOS tests. This way, nesting.children, eventhough
it doesn't inherit from parent, still has enough config to
actually complete the test. Otherwise, the qemu modules
would not be loaded, for example, and a nesting.children
statement would not evaluate.
* compton-git: 5.1-rc2 -> 6.2
vsync is now a boolean option, see:
https://github.com/yshui/compton/pull/130
menu-opacity is deprecated and there's a warning that says:
Please use the wintype option `opacity` of `popup_menu` and
`dropdown_menu` instead.
* nixos/compton: Keep vSync option backwards compatible
The new upstream option tries to make the best choice for the user.
Therefore the behaviour should stay the same with this backwards
compatibility patch.
* compton-git: Remove DRM option
It's deprecated and shouldn't be used.

* compton-git: Remove new_backends option
Was removed in "Let old/new backends co-exist"

Fix#61859.
Assertion fails when a Google Compute Engine image is built, because
now choices of filesystem types are restricted to `f2fs` and `ext` family if
auto-resizing is enabled.
This change will pin the filesystem used on such an image to be `ext4` for now.
Back in 2013, update-mime-database started using fdatasync() to write out
its changes after processing each file in /share/mime, with the reasoning
that a corrupted database from an interruption midway would be
problematic for applications[1]. Unfortunately, this caused a
significant regression in the time required to run update-mime-database:
commonly from under a second to half a minute or more.
This delay affects the time required to build system-path on NixOS, when
xdg.mime.enable is true (the default). For example, on one of my systems
system-path builds in ~48 seconds, 45 of which are update-mime-database.
This makes rapidly building new system configurations not fun.
This commit disables the calls to fdatasync(). update-mime-database
checks an environment variable, PKGSYSTEM_ENABLE_FSYNC, to determine
whether it should sync, and we can set this to false. system-path
already only has whatever filesystem commit guarantees that the Nix
builder provides. Furthermore, there is no risk of a failed MIME
database update messing up existing packages, because this is Nix.
(This issue was also reported at and discussed by Debian, Red Hat, and
Gentoo at least.)

This is actually very useful. Allows you to test switch-to-configuration
nesting.children is still currently still broken as it will throw
away 'too much' of the config, including the modules that make
nixos tests work in the first place. But that's something for
another time.
As a oneshot service, if the startup failed it would never be attempted again.
This is problematic when peer's addresses require DNS. DNS may not be reliably available at
the time wireguard starts. Converting this to a simple service with Restart
and RestartAfter directives allows the service to be reattempted, but at
the cost of losing the oneshot semantics.

Passwords should not be stored in plain text by default. On existing
installations the next time a users user accounts will automatically
be upgraded from plain to hashed one-by-one as they log in.
With `sshd -t` config validation for SSH is possible. Until now, the
config generated by Nix was applied without any validation (which is
especially a problem for advanced config like `Match` blocks).
When deploying broken ssh config with nixops to a remote machine it gets
even harder to fix the problem due to the broken ssh that makes reverts
with nixops impossible.
This change performs the validation in a Nix build environment by
creating a store path with the config and generating a mocked host key
which seems to be needed for the validation. With a broken config, the
deployment already fails during the build of the derivation.
The original attempt was done in #56345 by adding a submodule for Match
groups to make it harder screwing that up, however that made the module
far more complex and config should be described in an easier way as
described in NixOS/rfcs#42.
Some packages like `ibus-engines.typing-booster` require the dictionary
`fr_FR.dic` to provide proper support for the french language.
Until now the hunspell package set of nixpkgs didn't provide this
dictionary. It has been recommended to use `fr-moderne` as base and link
`fr_FR.dic` from it as done by other distros such as ArchLinux.
