The background color option is self-explanatory.
The mode is either `normal` or `stretch`, they are as defined by GRUB,
where normal will put the image in the top-left corner of the menu, and
stretch is the default, where it stretches the image without
consideration for the aspect ratio.

The default font is unreadably small on some hidpi displays. This
makes it possible to specify a TrueType or OpenType font at any point
size, and it will automatically be converted to the format the Grub
uses.
Restructure the nixos-artwork to make it easy to selectively
incorporate other components from upstream without needing to download
the full package.
Until now only the Gnome_Dark wallpaper was included. Add other
wallpapers available in the package repository.
Someone on IRC wanted to boot Fedora from another disk. While I'm not
too familiar with UEFI booting in conjunction with GRUB2 it took some
time to get it to work.
So in order to safe others from frustration I'm adding this as another
example to the extraEntries option.

This reverts commit c2b56626f1.
It broke creating the manual. I suspect the descriptions are
auto-wrapped by <para> and </para>.
We've been through this already in 3af715af90.
/cc #24978, @zraexy, @Mic92.
This reverts commit 656cc3acaf because it
causes building the manual to fail:
$ nixos-rebuild build

Using the --force option on GRUB isn't recommended, but there are very
specific instances where it makes sense. One example is installing on a
partitionless disk.
When Grub is to be used with UEFI, it is not going to write to any MBR
of any disk. As such, it is safe to use multiple "nodev" device entries
when mirroring the ESP partition to multiple disks.
E.g.:
```
boot.loader.grub = {
enable = true;
version = 2;
zfsSupport = true;
efiSupport = true;
mirroredBoots = [
{ devices = [ "nodev" ]; path = "/boot1"; efiSysMountPoint = "/boot1"; }
{ devices = [ "nodev" ]; path = "/boot2"; efiSysMountPoint = "/boot2"; }
{ devices = [ "nodev" ]; path = "/boot3"; efiSysMountPoint = "/boot3"; }
];
};
boot.loader.efi.canTouchEfiVariables = true;
```
Fixes#18584
Both btrfs-progs and utillinux are ~5MB, we may discuss in future
to handle this better but I see no better way at the moment than
increaing purity in the install process.
When displaying a warning about a removed Option we should always
include reasoning why it was removed and how to get the same
functionality without it.
Introduces such a description argument and patches occurences (mostly
with an empty string).
startGnuPGAgent: further notes on replacement
- add missing types in module definitions
- add missing 'defaultText' in module definitions
- wrap example with 'literalExample' where necessary in module definitions
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.

I tried to keep apparently-safe code in conflicts.
If /boot is a btrfs subvolume, it will be on a different device than /
but not be at the root from grub's perspective. This should be fixed in
a nicer way by #2449, but that can't go into 14.04.
Using pkgs.lib on the spine of module evaluation is problematic
because the pkgs argument depends on the result of module
evaluation. To prevent an infinite recursion, pkgs and some of the
modules are evaluated twice, which is inefficient. Using ‘with lib’
prevents this problem.
You can now say:
systemd.containers.foo.config =
{ services.openssh.enable = true;
services.openssh.ports = [ 2022 ];
users.extraUsers.root.openssh.authorizedKeys.keys = [ "ssh-dss ..." ];
};
which defines a NixOS instance with the given configuration running
inside a lightweight container.
You can also manage the configuration of the container independently
from the host:
systemd.containers.foo.path = "/nix/var/nix/profiles/containers/foo";
where "path" is a NixOS system profile. It can be created/updated by
doing:
$ nix-env --set -p /nix/var/nix/profiles/containers/foo \
-f '<nixos>' -A system -I nixos-config=foo.nix
The container configuration (foo.nix) should define
boot.isContainer = true;
to optimise away the building of a kernel and initrd. This is done
automatically when using the "config" route.
On the host, a lightweight container appears as the service
"container-<name>.service". The container is like a regular NixOS
(virtual) machine, except that it doesn't have its own kernel. It has
its own root file system (by default /var/lib/containers/<name>), but
shares the Nix store of the host (as a read-only bind mount). It also
has access to the network devices of the host.
Currently, if the configuration of the container changes, running
"nixos-rebuild switch" on the host will cause the container to be
rebooted. In the future we may want to send some message to the
container so that it can activate the new container configuration
without rebooting.
Containers are not perfectly isolated yet. In particular, the host's
/sys/fs/cgroup is mounted (writable!) in the guest.
