Indeed.  Even if you don’t use the declarative approach, usually just
upgrade everything (“guix upgrade”) and you won’t have any problems
either.

Problems arise when you try to upgrade only part of the packages.

Now, it doesn’t sound right that ‘util-linux’ is propagated from glib
and from poppler…?
