Dear Michael,

thank you, that helped. For good measure, I also kept
(simple-service 'my-kernel-module-loader-thunderbolt
kernel-module-loader-service-type
'("thunderbolt"))
(simple-service 'my-kernel-module-loader-v4l2loopback
kernel-module-loader-service-type
'("v4l2loopback"))
(simple-service 'my-kernel-module-loader-zram
kernel-module-loader-service-type
'("zram"))
Trying to add thunderbolt and zram to your code threw an error. I
suppose the difference is that v4l2loopback comes in its own Guix
package.
Reconfigure rebuilt the kernel then, but unfortunately in the end
failed with the below. What might be going on now?
All best,
Stefan
