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:

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.

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>

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.

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>
|
|
<prompt>$ </prompt>mkfs.ext4 /dev/sda1
|
|
<prompt>$ </prompt>mount /dev/sda1 /mnt
|
|
<prompt>$ </prompt>nixos-generate-config --root /mnt
|
|
<prompt>$ </prompt># edit /mnt/etc/nixos/configuration.nix
|
|
<prompt>$ </prompt>nixos-install
|
|
<prompt>$ </prompt>reboot
