The kernel default for `link_power_management_policy` is `"max_performance"`.
This commit:
f169f60575
set the NixOS default to `"min_performance"`.
This issue (https://github.com/NixOS/nixpkgs/issues/11276) details my long
journey to discover this after several file system failures incorrectly
attributed to `TRIM` and `NCQ` settings.
I think we should use the kernel default of `"max_performance"` to assure
the best experience for new users with SSDs and to conform to the defaults of
the kernel and other distros.
Option aliases/deprecations can now be declared in any NixOS module,
not just in nixos/modules/rename.nix. This is more modular (since it
allows for example grub-related aliases to be declared in the grub
module), and allows aliases outside of NixOS (e.g. in NixOps modules).
The syntax is a bit funky. Ideally we'd have something like:
options = {
foo.bar.newOption = mkOption { ... };
foo.bar.oldOption = mkAliasOption [ "foo" "bar" "newOption" ];
};
but that's not possible because options cannot define values in
*other* options - you need to have a "config" for that. So instead we
have functions that return a *module*: mkRemovedOptionModule,
mkRenamedOptionModule and mkAliasOptionModule. These can be used via
"imports", e.g.
imports = [
(mkAliasOptionModule [ "foo" "bar" "oldOption" ] [ "foo" "bar" "newOption" ]);
];
As an added bonus, deprecation warnings now show the file name of the
offending module.
Fixes #10385.
Trigger a restart of the post-resume.target on resume.
That allows other systemd services to receive the restart signal
after resume by becoming 'partOf' the post-resume.target.
This fixes #10077 because after some debugging it turns out that by
default we don't have a font which is able to display Chinese symbols.

With unifont we have a reasonable fallback font to ensure that every
written language is rendered correctly and thus less surprise for new
users who keep their font settings at the default.

The previous default was $out/lib/debug, which wasn't very useful.
This ensures that you can do
environment.systemPackages = [ pkgs.hello.debug ];
to install debug info.
`man 1 info` says:
The first non-option argument, if present, is the menu entry to
start from; it is searched for in all `dir' files along INFOPATH.
If it is not present, info merges all `dir' files and shows the
result. Any remaining arguments are treated as the names of menu
items relative to the initial node visited.
Which means that this does what previous programs/info did and #8519
(on-the-fly infodir generation for Emacs) wanted to do, but for both
programs.
This improves error messages when a set or a list is used where a path
was expected. For an example, if you used a package set (as opposed to a
single package) in systemPackages before this commit, the error was:
```
cannot coerce a list to a string, at "/home/nixpkgs/lib/types.nix":103:37
```
Now, the error message reads:
```
The option value `environment.systemPackages' in `/etc/nixos/configuration.nix' is not a list of paths.
```
Fixes #9110. Fontconfig recommends different precedence for rendering
settings and generic alias settings. To comply with the recommendations,
`98-nixos.conf` has been separated into `10-nixos-rendering.conf` and
`60-nixos-generic-alias.conf`.
