<refsection><title>Description</title>
<para>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>
<listitem><para>It copies Nix and its dependencies to
<filename>/mnt/nix/store</filename>.</para></listitem>
<listitem><para>It runs Nix in <filename>/mnt</filename> to build
the NixOS configuration specified in
<filename>/mnt/etc/nixos/configuration.nix</filename>.</para></listitem>
<listitem><para>It installs the GRUB boot loader on the device
specified in the option <option>boot.loader.grub.device</option>,
and generates a GRUB configuration file that boots into the NixOS
configuration just installed.</para></listitem>
<listitem><para>It prompts you for a password for the root
account.</para></listitem>
</itemizedlist>
</para>
<para>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.</para>
</refsection>
<refsection><title>Options</title>
<para>This command accepts the following options:</para>
<variablelist>
<varlistentry>
<term><option>--root</option></term>
<listitem>
<para>Defaults to <filename>/mnt</filename>. If this option is given, treat the directory
<replaceable>root</replaceable> as the root of the NixOS installation.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term><option>-I</option></term>
<listitem>
<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>
</listitem>
</varlistentry>
<varlistentry>
<term><option>--show-trace</option></term>
<listitem>
<para>Causes Nix to print out a stack trace in case of Nix expression evaluation errors.</para>
</listitem>
</varlistentry>
<varlistentry>
<term><option>--chroot</option></term>
<listitem>
<para>Chroot into given installation. Any additional arguments passed are going to be executed inside the chroot.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term><option>--help</option></term>
<listitem>
<para>Synonym for <command>man nixos-install</command>.</para>

<refsection><title>Examples</title>
<para>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
</screen>
