nixos/nixos-installer: add flags for verbosity and build logs
When installing a fresh NixOS system it occasionally happens that you
encounter issues that are rather hard to track down since
`nixos-install(8)` doesn't provide any debugging flags.

This patch adds `-L` to force `nix build` to display the build-log on
stderr and `-v` to increase the log-level of Nix.

09ac7cb55f nixos/nixos-option: Show values inside aggregate options uniformly
1. This makes aggregates of submodules (including the very important
"nixos-option users.users.<username>" case) behave the same way as any
other you-need-to-keep-typing-to-get-to-an-option-leaf (eg:
"nixos-option environment").

Before e0780c5:

  $ nixos-option users.users.root
  error: At 'root' in path 'users.users.root': Attribute not found
  An error occurred while looking for attribute names. Are you sure that 'users.users.root' exists?

After e0780c5 but before this change, this query just printed out a raw
thing, which is behavior that belongs in "nix eval", "nix-instantiate
--eval", or "nix repl <<<":

  $ nixos-option users.users.root
  {
    _module = {
      args = { name = "root"; };
      check = true;
    };
    createHome = false;
    cryptHomeLuks = null;
    description = "System administrator";
    ...

After this change:

  $ nixos-option users.users.root
  This attribute set contains:
  createHome
  cryptHomeLuks
  description
  extraGroups
  group
  hashedPassword
  ...

2. For aggregates of other types (not submodules), print out the option
that contains them rather than printing an error message.

Before:

  $ nixos-option environment.shellAliases.l
  error: At 'l' in path 'environment.shellAliases.l': Attribute not found
  An error occurred while looking for attribute names. Are you sure that 'environment.shellAliases.l' exists?

After:

  $ nixos-option environment.shellAliases.l
  Note: showing environment.shellAliases instead of environment.shellAliases.l
  Value:
  {
    l = "ls -alh";
    ll = "ls -l";
    ls = "ls --color=tty";
  }
  ...

e0780c5cff
nixos/nixos-option: fix evaluator to render a full submodule entry
When running e.g. `nixos-option users.users.ma27`, the evaluation breaks
since `ma27` is the attribute name in `attrsOf (submodule {})`, but not
a part of the option tree and therefore breaks with the following
errors:

```
error: At 'ma27' in path 'users.users.ma27': Attribute not found
An error occurred while looking for attribute names. Are you sure that 'users.users.ma27' exists?
```

This happens since the option evaluator expects that either the option
exists or the option is a submodule and the "next" token in the
attribute path points to an option (e.g. `users.users.ma27.createHome`).

This patch checks in the `Attribute not found` condition if the attribute-path
actually exists in the config tree. If that's true, a dummy-attrset is created
which contains `{_type = "__nixos-option-submodule-attr";}`, in that case, the
entire entry of the submodule will be displayed.

84d55716a9 Don't print header on stderr
Automated consumers can use 'sed 1d' or similar to remove this header.

This probably makes this output *easier* to consume correctly.  Having
this header show up in consumers' terminal or log output is probably not
useful, but hiding it without hiding all error messages would have been
more troublesome that just stripping it from stdout.

I.e., previously, unsophisticated use would show undesired output:
  $ some-other-tool
  This attribute set contains:
  This attribute set contains:
  This attribute set contains:
  This attribute set contains:
  <Actual some-other-tool output>

The simplest way to hide this undesired output would have been
nixos-option ... 2>/dev/null, which would hide all error messages.
We do not wish to encourage that.

Correct use would have been something like:
  nixos-option ... 2> >( grep --line-buffered -v 'This attribute set contains:')

After this change, correct use is simpler:
  nixos-option ... | sed 1d
or
  nixos-option ... | sed '1/This attribute set contains:/d'
if the caller don't know if this invocation of nixos-option will yield
an attribute listing or an option description.

88183eb484 Per reviewer request, cast the other side.
I don't think this matters.  As long as one or the other of these is
a std::string, I get an operator== that looks at content rather than
pointer equality.  I picked casting the constant over casting the dynamic
thing in hopes that the compiler would have a better chance at optimizing
away any runtime cost.

Deferring to reviewer.

263a81e285 nixos-rebuild: support sudo + --target-host
This adds support for deploying to remote hosts without being root:

  sudo nixos-rebuild --target-host non-root@host

Without this change, only root@host is able to deploy.

The idea is that if the local command is run with sudo, so should the
remote one, thus there is no need for adding any CLI options.

That is because fish requires env to set environment variables for a program. It should also work on other shells.

9e45f6feac nixos-generate-config: don't generate swapDevices for *files*
Up until now, the output has been the same for swap devices and swap
files:

  { device = "/var/swapfile"; }

Whereas for swap *files* it's easier to manage them declaratively in
configuration.nix:

  { device = "/var/swapfile"; size = 8192; }

(NixOS will create the swapfile, and later resize it, if the size
attribute is changed.)

With the assumption that swap files are specified in configuration.nix,
it's silly to output them to hardware-configuration.nix.

c3d22fdca1 nixos-generate-config: Include extraGroups "wheel"
I've been asked, on numerous occasions, by my students and others, how
to 'sudo' on NixOS.

Of course new users could read up in the manual on how to do that, or we
could make it more accessible for them by simply making it visible in
the default `configuration.nix` file.

Additionally, as raised in [1], replacing `guest` with something more
recognizable could be potentially beneficial to new users. I've
opted for `jane` for now.

cpufreq: add option for setting the cpu max and min frequencies
This adds a NixOS option for setting the CPU max and min frequencies
with `cpufreq`.  The two options that have been added are:

- `powerManagement.cpufreq.max`
- `powerManagement.cpufreq.min`

It also adds an alias to the `powerManagement.cpuFreqGovernor` option as
`powerManagement.cpufreq.governor`.  This updates the installer to use
the new option name.  It also updates the manual with a note about
the new name.

nixos-build-vms: fix eval
Previously I got the following error message:

```
error: opening file '/home/ma27/Projects/nixpkgs/nixos/modules/installer/default.nix': No such file or directory
```

Probably related to 6c68fbd4e1.

Revert "Merge pull request #48122 from zimbatm/pkg-nixos-rebuild"
This reverts commit 10addad603, reversing
changes made to 7786575c6c.

NixOS scripts should be kept in the NixOS source tree, not in
pkgs. Moving them around is just confusing and creates unnecessary
code/history churn.

nixos-*: init as package
Move all the nixos-* scripts from the nixos distribution as real
packages in the pkgs/ package set.

This allows non-nixos users to run the script as well. For example,
deploying a remote machine with:

    nixos-rebuild --target-host root@hostname --build-host root@hostname

7748c3da1b nixos/nixos-install: Unset system
The system variable is used from the (possibly polluted) shell
environment.
This causes nixos-install to fail in a nix-shell because the system
shell variable is automatically set to the current system (e.g.
x86_64-linux).

nixos-option: don't abort with shell failures if options are not existant
`nixos-option` basically handles two cases: the given option is either a
valid option defined using `mkOption` or an attribute set which contains
a set of options.

If none of the above cases is valid, `$1` is invalid. Unfortunatley the
script interpreted invalid options as an attribute set which rendered
shell failures when trying to evaluate the arguments.

First of all, `if names=$(attrNames ...)` resulted in `<PRIMOP>` as
`attrNames` simply evaluated `builtins.attrNames $result` which results
in a non-applied function with `$result` being empty. Trying to map over
this string using `nixMap` while applying `escapeQuotes` causes the bash
error as `eval echo "<PRIMOP>"` is invalid syntax.

Explicitly checking if `$result' contains a value (do we have an
attribute set?) and otherwise returning a warning and asking if $option
exists fixes the problem.

Fixes #48060

nixos-option: fix #47722 when missing ~/.nix-defexpr/channels
The problem was that the non-fatal warning was not omitted
from the output when constructing a nix expression.
Now it seems OK for me.  When return code is OK,
the warnings don't get passed anywhere, but I expect
that won't matter for this utility.  Fatal errors are still shown.
