Re: to save my Guix System installation

[Skyler <skyvine@protonmail.com>]

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
