[ludo@gnu.org (Ludovic Courtès)]

Clément Lassieur <clement@lassieur.org> skribis:

> This distinguishes fields whose order matters, and makes sure further changes
> won't inadvertently change the order.
>
> * gnu/services/cgit.scm (serialize-cgit-configuration): New procedure that
> serializes fields with a precise order.
> (cgit-activation): Replace the generic SERIALIZE-CONFIGURATION with
> SERIALIZE-CGIT-CONFIGURATION.
