Next I added the following to my system.scm: (services (append (list ... (simple-service 'my-kernel-module-loader-v4l2loopback kernel-module-loader-service-type '("v4l2loopback")) ... ) %desktop-services)) and reconfigured, but the module was still not loaded. Even manual sudo modprobe v4l2loopback fails with modprobe: FATAL: Module v4l2loopback not found in directory /run/booted-system/kernel/lib/modules/5.17.1 What am I supposed to do? All best, Stefan
