Hi again,

in my config.scm if I add this part

(guix-service-type
 >    config => (guix-configuration
 >      (inherit config)
 >      (extra-options (list "--gc-keep-derivations=yes" 
"--gc-keep-outputs=yes"))

at the end of my guix-service-types,
it seems to me there I have to make 4 brackets:
Or am I wrong?



My config.scm:
