This command installs NixOS in the file system mounted on
|
|
<filename>/mnt</filename>, based on the NixOS configuration specified in
|
|
<filename>/mnt/etc/nixos/configuration.nix</filename>. It performs the
|
|
following steps:
|

<itemizedlist>
|

<para>

It copies Nix and its dependencies to

It installs the GRUB boot loader on the device specified in the option
|
|
<option>boot.loader.grub.device</option> (unless
|
|
<option>--no-bootloader</option> is specified), and generates a GRUB
|
|
configuration file that boots into the NixOS configuration just
|
|
installed.

This command is idempotent: if it is interrupted or fails due to a temporary

problem (e.g. a network issue), you can safely re-run it.

<option>--root</option>

<para>

Defaults to <filename>/mnt</filename>. If this option is given, treat the
|
|
directory <replaceable>root</replaceable> as the root of the NixOS
|
|
installation.

If this option is provided, <command>nixos-install</command> will install
|
|
the specified closure rather than attempt to build one from
|
|
<filename>/mnt/etc/nixos/configuration.nix</filename>.
|
|
</para>
|
|
<para>
|
|
The closure must be an appropriately configured NixOS system, with boot
|
|
loader and partition configuration that fits the target host. Such a
|
|
closure is typically obtained with a command such as <command>nix-build
|
|
-I nixos-config=./configuration.nix '<nixos>' -A system
|
|
--no-out-link</command>

<para>
|
|
Add a path to the Nix expression search path. This option may be given
|
|
multiple times. See the NIX_PATH environment variable for information on
|
|
the semantics of the Nix search path. Paths added through
|
|
<replaceable>-I</replaceable> take precedence over NIX_PATH.

<para>
|

Sets the maximum number of build jobs that Nix will perform in parallel
|
|
to the specified number. The default is <literal>1</literal>. A higher

|
value is useful on SMP systems or to exploit I/O latency.

<para>

|
Sets the value of the <envar>NIX_BUILD_CORES</envar> environment variable
|
|
in the invocation of builders. Builders can use this variable at their
|
|
discretion to control the maximum amount of parallelism. For instance, in
|
|
Nixpkgs, if the derivation attribute
|
|
<varname>enableParallelBuilding</varname> is set to
|
|
<literal>true</literal>, the builder passes the
|
|
<option>-j<replaceable>N</replaceable></option> flag to GNU Make. The
|
|
value <literal>0</literal> means that the builder should use all
|
|
available CPU cores in the system.

A typical NixOS installation is done by creating and mounting a file system
|
|
on <filename>/mnt</filename>, generating a NixOS configuration in
|
|
<filename>/mnt/etc/nixos/configuration.nix</filename>, and running
|
|
<command>nixos-install</command>. For instance, if we want to install NixOS
|
|
on an <literal>ext4</literal> file system created in
|
|
<filename>/dev/sda1</filename>:
|
|
<screen>
|
|
$ mkfs.ext4 /dev/sda1
|
|
$ mount /dev/sda1 /mnt
|
|
$ nixos-generate-config --root /mnt
|
|
$ # edit /mnt/etc/nixos/configuration.nix
|
|
$ nixos-install
|
|
$ reboot
