Re: to save my Guix System installation

[Skyler]

If you declared all your packages in the file that contains your 
operating-system definition then you can just save that file and point a new 
guix installation towards it to restore your configuration. If you've run 
imperative commands (for example, `guix install some-package`) then you'll need 
to record those separately, `guix package -I` will list all of the packages 
that you've installed imperatively. I'm not sure about other imperative 
actions, I'm obsessive about doing things declaratively exactly because it 
makes this kind of situation easy to deal with (I have a habit of bungling up 
my machines and needing to install them fresh). If you can share more details 
about how you have configured your guix system then I might be able to offer 
more specific advice.

Of course, this will do nothing to save your data, if you have data documents 
or other files in your home directory that are not system configuration then 
those will need to be saved separately in either case.

Sincerely,
Skyler
