Indeed.  Even if you don=E2=80=99t use the declarative approach, usually ju=
st
upgrade everything (=E2=80=9Cguix upgrade=E2=80=9D) and you won=E2=80=99t h=
ave any problems
either.

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

Now, it doesn=E2=80=99t sound right that =E2=80=98util-linux=E2=80=99 is pr=
opagated from glib
and from poppler=E2=80=A6?
