`prefer-remote-fetch` 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:
|
||
|
|
|
||
|
|
```nix
|
||
|
|
self: super:
|
||
|
|
(super.prefer-remote-fetch self super)
|
||
|
|
```
|
||
|
|
|
||
|
|
A full configuration example for that sets the overlay up for your own account, could look like this
|
||
|
|
|
||
|
|
```ShellSession
|
||
|
|
$ mkdir ~/.config/nixpkgs/overlays/
|
||
|
|
$ cat > ~/.config/nixpkgs/overlays/prefer-remote-fetch.nix <<EOF
|
||
|
|
self: super: super.prefer-remote-fetch self super
|
||
|
|
EOF
|
||
|
|
```
