Hi,

Julien Lepiller <julien@lepiller.eu> skribis:

> On a recently installed system, I ran guix install coq -n. Guix told me i=
t would download 270 MB and do 4 hooks. Guix install coq however told me it=
 will 521 MB (which it did) including a lot more packages (including coq:id=
e),the same 4 hooks with different store hashes and additional grafts. This=
 was quite unexpected :)

Yes, the difference is due to the current implementation of grafts
(=E2=80=98--dry-run=E2=80=99 implies =E2=80=98--no-grafts=E2=80=99).  It=E2=
=80=99s unfortunate, but there=E2=80=99s no
easy workaround, I think.
