Hi,
Re-reading, I am missing one point…

This wpxqqdcslxxx9g9l9j847ifgh0xdlsfl-emacs-no-x-tarball-pack.tar.gz is
what you get before “guix pull”. It means, it used the Guix revision
packaged by Debian (Guix v1.4 I guess).
Then after “guix pull”, I read
pszvzh7917kkf1cisxd46bx8vlac25zh-emacs-no-x-tarball-pack.tar.gz which
seems different. This had been produced using Guix revision 65dcfb3.
Well, I am on x86_64, here what I get:
--8<---------------cut here---------------start------------->8---
$ guix time-machine --commit=v1.4.0 -- pack -R -S /emacsbin=bin emacs-no-x
/gnu/store/pndklr1v6h3lm2x2pks43hb0ra8fp8fb-emacs-no-x-tarball-pack.tar.gz
$ guix time-machine --commit=65dcfb3f3865d08467da747041263fd22460d393 -- pack
-R -S /emacsbin=bin emacs-no-x
/gnu/store/kha2n6qzvyc178jkymf5ddapxr225yvj-emacs-no-x-tarball-pack.tar.gz
--8<---------------cut here---------------end--------------->8---
And I guess your scenario reads,
--8<---------------cut here---------------start------------->8---
root@arm-vm:~# apt install guix
root@arm-vm:~# guix pack -R -S /emacsbin=bin emacs-no-x
/gnu/store/wpxqqdcslxxx9g9l9j847ifgh0xdlsfl-emacs-no-x-tarball-pack.tar.gz
root@arm-vm:~# guix pull
root@arm-vm:~# guix pack -R -S /emacsbin=bin emacs-no-x
/gnu/store/pszvzh7917kkf1cisxd46bx8vlac25zh-emacs-no-x-tarball-pack.tar.gz
--8<---------------cut here---------------end--------------->8---
Is it not the case? Well, I guess you get:
--8<---------------cut here---------------start------------->8---
root@arm-vm:~# /usr/bin/guix pack -R -S /emacsbin=bin emacs-no-x
/gnu/store/wpxqqdcslxxx9g9l9j847ifgh0xdlsfl-emacs-no-x-tarball-pack.tar.gz
root@arm-vm:~# guix time-machine
--commit=65dcfb3f3865d08467da747041263fd22460d393 \
-- pack -R -S /emacsbin=bin emacs-no-x
/gnu/store/pszvzh7917kkf1cisxd46bx8vlac25zh-emacs-no-x-tarball-pack.tar.gz
--8<---------------cut here---------------end--------------->8---
No? Do you see something different?
Cheers,
