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

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 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
|

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.
