It is from Oct. 2021. The pack built by the post is: /gnu/store/6rga6pz60di21mn37y5v3lvrwxfvzcz9-python-python-numpy-docker-pack= .tar.gz comparing with today, using 9d795fb and the time-machine: --8<---------------cut here---------------start------------->8--- $ guix time-machine -C /tmp/channels.scm \ -- pack -f docker --save-provenance -m /tmp/manifest.scm /gnu/store/ryqvz83s11qb96d9i6ywv08vcshg6k17-python-python-numpy-docker-pack= .tar.gz --8<---------------cut here---------------end--------------->8--- Note that =E2=80=99docker images=E2=80=99 said ea2d5e62b2d2 when now it says e0a073dfa1ec.=20 The channels.scm and manifest.scm files are the exact same =E2=80=93 or the= bug is between my keyboard and my chair. ;-) Even, following the post, let compare: --8<---------------cut here---------------start------------->8--- $ tree gnu gnu =E2=94=94=E2=94=80=E2=94=80 store =E2=94=94=E2=94=80=E2=94=80 vdf5c49kzsmdm70134fdgy418ifxd7kh-profile =E2=94=94=E2=94=80=E2=94=80 manifest 2 directories, 1 file --8<---------------cut here---------------end--------------->8--- and the post provides ia1sxr3qf3w9dj7y48rwvwyx289vpfgi-profile. --8<---------------cut here---------------start------------->8--- $ guix package -p gnu/store/vdf5c49kzsmdm70134fdgy418ifxd7kh-profile/ --exp= ort-channels ;; This channel file can be passed to 'guix pull -C' or to ;; 'guix time-machine -C' to obtain the Guix revision that was ;; used to populate this profile.

The package =E2=80=99python=E2=80=99 does not build r= eproductibly but that should not change the hash of the profile nor the pack, it should only change the hash of the =E2=80=99docker images=E2=80=99. What do I miss? Cheers, simon
