The correct way to override a single value would be to use something
like this:
systemd.services.nagios.serviceConfig.Restart = lib.mkForce "no";
However, this doesn't work because the check is applied for the attrsOf
type and thus the attribute values might still contain the attribute set
created by mkOverride.
The unitOption type however did already account for this, but at this
stage it's already too late.
So now the actual value is unpacked while checking the values of the
attribute set, which should allow us to override values in
serviceConfig.

When a package contains a directory in one of the systemd directories
(like flatpak does), it is symlinked into the *-units derivation.
Then later, the derivation will try to create the directory, which
will fail:
mkdir: cannot create directory '/nix/store/…-user-units/dbus.service.d': File exists
builder for '/nix/store/…-user-units.drv' failed with exit code 1
Closes: #33233
GRUB 2.0 supports png, jpeg and tga. This will use the image's suffix to
load the right module.
As jpeg module is named jpeg, jpg is renamed jpeg.
If the user uses wrong image suffix for an image, it wouldn't work anyway.
This will leave up to two additional left-over files in /boot/ if user switches
through all the supported file formats. The module already left the png
image if the user disabled the splash image.
This is apparent from the service file directory in plymouth:
├── multi-user.target.wants
│ ├── plymouth-quit.service -> ../plymouth-quit.service
│ └── plymouth-quit-wait.service -> ../plymouth-quit-wait.service
Leaving it unspecified caused gdm-wayland to crash on boot, see #39615.
The change made other display managers not quit plymouth properly however. By
removing "multi-user.target" from `plymouth-quit.after` this is resolved.
The isKexecable flag treated Linux without kexec as just a normal
variant, when it really should be treated as a special case incurring
complexity debt to support.

At one point in my configuration I had:
boot.kernel.sysctl = {
# https://unix.stackexchange.com/questions/13019/description-of-kernel-printk-values
"kernel.printk" = "4 4 1 7";
};
which triggered:
error: The unique option `boot.kernel.sysctl.kernel.printk' is defined multiple times, in `/home/teto/dotfiles/nixpkgs/mptcp-unstable.nix' and `/home/teto/nixpkgs/nixos/modules/system/boot/kernel.nix'.

This simple addition allows to override it.
This option, if set to true, enables fallbacking to an interactive
passphrase prompt when the specified keyFile is not found.
The default is false, which is compatible with previous behavior and
doesn't prevent unattended boot.
Regression introduced by 801c920e95.
Since then, the btrfsSimple subtest of the installer VM test fails with:
Btrfs did not return a path for the subvolume at /
The reason for this is that the output for "btrfs subvol show" has
changed between version 4.8.2 and 4.13.1.
For example the output of "btrfs subvol show /" in version 4.8.2 was:
/ is toplevel subvolume
In version 4.13.1, the output now is the following and thus the regular
expressions used in nixos-generate-config.pl and install-grub.pl now
match (which results in the error mentioned above):
/
Name: <FS_TREE>
UUID: -
Parent UUID: -
Received UUID: -
Creation time: -
Subvolume ID: 5
Generation: 287270
Gen at creation: 0
Parent ID: 0
Top level ID: 0
Flags: -
Snapshot(s):
In order to fix this I've changed nixos-generate-config.pl and
install-grub.pl, because both use "btrfs subvol show" in a similar vein,
so the regex for parsing the output now doesn't match anymore whenever
the volume path is "/", which should result in the same behaviour as we
had with btrfs-progs version 4.8.2.
Tested against the btrfsSimple, btrfsSubvols and btrfsSubvolDefault
subtests of the installer VM test and they all succeed now.

* the keyboard modules in all-hardware.nix are already defaults of
boot.initrd.availableKernelModules
* ide modules, hid_lenovo_tpkbd and scsi_wait_scan have been removed
because they're not available anymore
* i8042 was a duplicate (see few lines abowe)
the systemd.unit(5) discussion of wantedBy and requiredBy is in the
[Install] section, and thus focused on stateful 'systemctl enable'.
so, clarify that in NixOS, wantedBy & requiredBy are still what most
users want, and not to be confused with enabled.
