<title>prefer-remote-fetch overlay</title>
<para>
<function>prefer-remote-fetch</function> is an overlay that download sources
on remote builder. This is useful when the evaluating machine has a slow
upload while the builder can fetch faster directly from the source. To use
it, put the following snippet as a new overlay:
<programlisting>
self: super:
(super.prefer-remote-fetch self super)
</programlisting>
A full configuration example for that sets the overlay up for your own
account, could look like this
<screen>
<prompt>$ </prompt>mkdir ~/.config/nixpkgs/overlays/
<prompt>$ </prompt>cat &gt; ~/.config/nixpkgs/overlays/prefer-remote-fetch.nix &lt;&lt;EOF
self: super: super.prefer-remote-fetch self super
EOF
</screen>
