8 <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:
9<programlisting>
10self: super:
11 (super.prefer-remote-fetch self super)
12</programlisting>
13 A full configuration example for that sets the overlay up for your own account, could look like this
14<screen>
15<prompt>$ </prompt>mkdir ~/.config/nixpkgs/overlays/
16<prompt>$ </prompt>cat > ~/.config/nixpkgs/overlays/prefer-remote-fetch.nix <<EOF
17 self: super: super.prefer-remote-fetch self super
