I see this too, especially since the glibc graft, because all packages
are now grafted.  Here’s a package I have just built with “guix build
axoloti”.  Then I go offline and try to install it:

--8<---------------cut here---------------start------------->8---
guix package -i axoloti

The following package will be upgraded:
   axoloti      1.0.12 → 1.0.12 
/gnu/store/v74k2b6mivsmz1q00slpl9dxjlg9qa3r-axoloti-1.0.12

The same is true for running “guix build” for a package that has already
been built:

I can avoid the “guix build” problem by passing “--no-grafts”.
