It=E2=80=99s not really =E2=80=9Ceach node=E2=80=9D but rather =E2=80=9Cmos= t nodes.=E2=80=9D :-) The daemon keeps track of all the references of each item, including self-references. And it turns out that most packages record their $prefix in their binaries, for instance, hence the self-reference. This can be seen with =E2=80=98guix gc --references=E2=80=99 as well. Ludo=E2=80=99.
