Hi Guixers,

thanks for the answer.

I changed my config.scm to:

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

and after:
gfp@Tuxedo ~$ sudo guix system reconfigure /etc/config.scm

it said:

/etc/config.scm:38:12: Fehler: (service guix-service-type config => 
(guix-configuration (inherit config) (extra-options (list 
"--gc-keep-derivations=yes" "--gc-keep-outputs=yes")))): source 
expression failed to match any pattern
