NB: in this setting, the cache only grows. It might be manually deleted when it becomes too bloated but smarter eviction strategies can be implemented too! | NB: in this setting, the cache only grows.

== Enable sandboxed builds == | |||
At the moment travis does not have a sandbox enabled by default. | |||
This can lead to non-trivial to reproduce errors, | |||
when files from the travis image interfere with the build. | |||
Enabling however is straight-forward by using the following little snippet: | |||
<syntaxHighlight lang=nix> | |||
before_script: | |||
- sudo mkdir -p /etc/nix && echo 'sandbox = true' | sudo tee /etc/nix/nix.conf | |||
</syntaxHighlight> | |||
