No, not necessarily. I could no longer do 'guix pull && guix system reconfigure ...', which I attempted to solve by upstreaming this patch. I wonder if anyone else is having the same problem on this hardware.. Thanks for your snippet! I've done a system reconfigure and the extra configuration applied as expected. If there is anyone with the same problem, we could look further into upstreaming it. Thanks, Roel
