Advanced users may wish to install NixOS using an existing PXE or iPXE setup.

</para>

<para>
|
||
These instructions assume that you have an existing PXE or iPXE
|
||
infrastructure and simply want to add the NixOS installer as another option.
|
||
To build the necessary files from a recent version of nixpkgs, you can run:
|
||
</para>
|
||
|
||
<programlisting>
|
||
nix-build -A netboot.x86_64-linux nixos/release.nix
|
||
</programlisting>
|
||
|
||
<para>
|
||
This will create a <literal>result</literal> directory containing: *
|
||
<literal>bzImage</literal> – the Linux kernel * <literal>initrd</literal>
|
||
– the initrd file * <literal>netboot.ipxe</literal> – an example ipxe
|
||
script demonstrating the appropriate kernel command line arguments for this
|
||
image
|
||
</para>
|
||
|
||
<para>
|
||
If you’re using plain PXE, configure your boot loader to use the
|
||
<literal>bzImage</literal> and <literal>initrd</literal> files and have it
|
||
provide the same kernel command line arguments found in
|
||
<literal>netboot.ipxe</literal>.
|
||
</para>
|
||
|
||
<para>
|
||
If you’re using iPXE, depending on how your HTTP/FTP/etc. server is
|
||
configured you may be able to use <literal>netboot.ipxe</literal> unmodified,
|
||
or you may need to update the paths to the files to match your server’s
|
||
directory layout
|
||
</para>
|
||
|
||
<para>
|
||
In the future we may begin making these files available as build products
|
||
from hydra at which point we will update this documentation with instructions
|
||
on how to obtain them either for placing on a dedicated TFTP server or to
|
||
boot them directly over the internet.
