Re: Garbage Collector

Hi again,

in my config.scm if I add this part

(guix-service-type
>    config => (guix-configuration
>      (inherit config)


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:

Hi,

The manual says that it is dangerous to use: "guix gc"
because it can delete too much.

I agree that 'guix gc' deletes too much, but it's probably not
dangerous. You will just see some downloads and builds repeated when
reconfiguring later.

I believe 'guix gc' deletes items that are not garbage to me (but I am
new to Guix). Based on friendly advice I received, I currently use
these settings:

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

Kind regards
