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?
