Subject: [bug#54997] [PATCH v2 02/15] file-systems: Avoid load-time warnings when attempting to load (guix store).
Date: Wed, 27 Apr 2022 18:56:22 +0200

This makes sure warnings like "incompatible bytecode version" don't go
through when looking for (guix store).

* gnu/system/file-systems.scm (%store-prefix): Parameterize
'current-warning-port' around 'resolve-module' call.
