Subject: [bug#77578] [PATCH 1/2] tests: docker-system: Remove unnecessary services from Docker image.
Date: Fri,  6 Jun 2025 23:15:38 +0300

These services aren't needed in containers since:
- udev requires device tree access controlled by the container runtime
- urandom-seed depends on udev service

* gnu/tests/docker.scm (%test-docker-system): Remove udev-service-type,
urandom-seed-service-type.
