Avoids this warning when running `nixos-rebuild switch`:
````

trace: Obsolete option `services.virtualboxGuest.enable' is used. It was renamed to `virtualisation.virtualbox.guest.enable'.
````
This option requests compatibility with older NixOS releases with
respect to stateful data, in cases where new releases have defaults
that might be incompatible with system state of existing NixOS
deployments. For instance, if we change the default version of
PostgreSQL, existing deployments will break if the new version can't
read databases created by the old version.
So for example, setting
system.stateVersion = "15.07";
requests that options like services.postgresql.package use defaults
corresponding to the 15.07 release branch. Note that
nixos-generate-config emits this option. (In the future, NixOps may
set system.stateVersion to the NixOS release in use when the machine
was created.)
See also #7939 for another motivating example.
Especially new users could be confused by this, so we're now marking
services.virtualbox.enable as obsolete and defaulting to
services.virtualboxGuest.enable instead. I believe this now makes it
clear, that this option is for guest additions only.

The NixOS manual says modules have the following signature:
{ config, lib, pkgs, ... }:
But our generated configuration.nix file lacks the 'lib' part. Add it.
The host id value gets generated by reading a 32-bit value from
/dev/urandom.
This makes programs that rely on a correct host id more reliable.
It also makes using ZFS more seamless, as you don't need to configure
the hostId manually; instead, it becomes part of your config from the
moment you install NixOS.
This reverts commit 469f22d717, reversing
changes made to 0078bc5d8f.

I tried to keep apparently-safe code in conflicts.
An escape char is needed to prevent "$ nix" from being evaluated and
expanded to an empty string. With this change the resulting text is
$ nix-env -qaP | grep wget
instead of
-env -qaP | grep wget
Dmidecode fails in our EFI test with the error "SMBIOS entry point
missing". But we don't need dmidecode because we have already have
systemd-detect-virt.
Fixes #2379.
The new name was a misnomer because the values really are X11 video
drivers (e.g. ‘cirrus’ or ‘nvidia’), not OpenGL implementations. That
it's also used to set an OpenGL implementation for kmscon is just
confusing overloading.
We don't want to hardcode configuration options that the current kernel chose
for us when mounting the filesystem, since the defaults can change in the
future.
IIUC, <nixos> is going to be deprecated someday in the future, and as
most of those references are already replaced I guess it's safe to
replace it here as well, as it is only relevant on new/updated
installations.

It's already set in hardware-configuration.nix so this just confuses
people.
Also get rid of boot.initrd.kernelModules, since
hardware-configuration.nix is supposed to figure that out as well.
So, we get the old behaviour of nixos-hardware-scane if we run the
following command:
nixos-generate-config --no-filesystems --show-hardware-config
This allows to use scripts in order to fetch NixOS specific hardware
information, without the need to duplicate code elsewhere.

The attributes swapDevices and imports add a space character after the
eqals sign, which is unnecessary. I know, I'm a pedantic douche bag but
it hurts my eyes.

This is to get back the old behavior of nixos-hardware-scan, which
didn't include fileSystems and swapDevices.

If this option is given, nixos-generate-config will write the
configuration to /etc/nixos under the given root, and only emit
fileSystems attributes for filesystems under the given root directory.
The typically use case is at installation time, where you can say:
$ nixos-generate-config --root /mnt
which will create /mnt/etc/nixos/{configuration.nix,hardware-configuration.nix}.
Also add a --force flag to force overwriting configuration.nix.
