This script would always "detect" the "powersave" governor as it is available on
practically all CPUs while the "ondemand" governor is only available on some old
CPUs.
IME the "powersave" governor barely provides any power savings but introduces
massive performance deficits, including noticable stuttering. This is not the
default experience we should offer users, even for those who use laptops.
Use the kernel default (currently "performance", CPU makers may change it in
future) instead.
[Motivation](https://github.com/NixOS/nixpkgs/issues/257817#issuecomment-1741705042):
- Having all the XKB options in the same attribute set clarifies their
relation better than using a common option name prefix ("xkb").
- `services.xserver.layout` is an XKB option, but this is not obvious
from its name. Putting it with the other XKB options clarifies this.

- Move contents of README.md from
nixos/modules/installer/tools/manpages/ to
nixos/doc/manual/contributing-to-this-manual.chapter.md.
- Don't mention DocBook as its obsolete and too specific.
- Rename derivation attribute name of configuration.nix(5) manual page,
both on the `contributing-to-this-manual.chapter.md`, and in other
places.
Since each such `nixos-*` tool has it's own derivation, exposed in pkgs,
There is no point in separating the manuals from the packages. If
someone wishes to have the tools without the manuals, they can use
meta.outputsToInstall to disable the installation of the manpages of
these packages. This Fixes#244450.
After building the target system, `nixos-install` tries to remove `/mnt`
on the target filesystem. And the script may fail without any explanation,
if `/mnt` isn't empty.
This commit makes the installation process carry on even if there are
files under `/mnt`.
See https://github.com/NixOS/nixpkgs/issues/244643.
Although 'lib' isn't needed by the default configuration, new NixOS uses
can get confused when being recommended configuration.nix snippets like
systemd.services.NetworkManager-wait-online.enable = lib.mkForce false;
and have `sudo nixos-rebuild switch` fail with
error: undefined variable 'lib'
swraid support will now only be enabled by default if stateVersion is
older than 23.11. nixos-generate-config will now generate explicit
config for enabling support if needed.
The single option tries to do too much work, which just ends up confusing people.
So:
- don't force the console font, the kernel can figure this out as of #210205
- don't force the systemd-boot mode, it's an awkward mode that's not supported
on most things and will break flicker-free boot
- add a separate option for the xorg cursor scaling trick and move it under the xorg namespace
- add a general `fonts.optimizeForVeryHighDPI` option that explicitly says what it does
- alias the old option to that
- don't set any of those automatically in nixos-generate-config
Guest operating systems inside VMs or containers can't update the host CPU's microcode for obvious security reasons, so setting the `hardware.cpu.*.updateMicrocode` options is pointless.
adding two graphical programs makes a strong assmuption that users will
use a graphical environment.
add a command line program as an alternative suggestion that is easy to
comment in as a first-steps measure.
