This should be the option you are looking for.

FYI you can do:

nixos-rebuild switch --flake git+https://yourgithost.com/yourrepo

I’ve only been using it for about a year, but as of now I can’t imagine ever going back to imperative system configuration. Having my infrastructure declared in its entirety by a version controlled code base is just too comfy.

Glad to help! Just keep in mind that what you’re doing there is dumping the entire dconf settings tree and applying it as is. That will include a lot of things you don’t want/care about, including state data of certain applications. You should probably sift through the dump file and throw stuff out before loading it again, but I’m sure you’ll figure it out.

export settings on old pc:

dconf dump / > dconf-settings.dump

import on new pc:

cat dconf-settings.dump | dconf load /

Whatever comes with GNOME/gdm.

NixOS! 💪
