Well, I meant what I wrote in the example below

> ...

It deletes the old ~/.config/guix/ profiles.  If I'm not wrong, each of those
profiles consume a couple of 100MBs.

So if "checkout" is confusing, what about "Guix copy" instead?

See "(guix) Invoking guix pull" in the manual for terminology.

I like it better!  I'll use your suggestion.
