“cache” build failures, meaning that it will remember (in its

database) that a derivation previously failed. If you then try to

build the derivation again, Nix will immediately fail rather than
|

perform the build again. Failures in fixed-output derivations
|

(such as <function>fetchurl</function> calls) are never cached.

The “failed” status of a derivation can be cleared using

<command>nix-store --clear-failed-paths</command>. By default,

failure caching is disabled.</para></listitem>
