Aha indeed that makes perfect sense! I just re-checked and the two
"hints", including setting PATH after the first guix pull, are exactly
to the point:

root@vm-remarkable2:~# type -P guix
root@vm-remarkable2:~# GUIX_PROFILE="/root/.config/guix/current"
root@vm-remarkable2:~# . "$GUIX_PROFILE/etc/profile"
root@vm-remarkable2:~# type -P guix
root@vm-remarkable2:~# hash guix  # only makes sense after updating PATH
root@vm-remarkable2:~# type -P guix

>>> root@arm-vm:~# /usr/bin/guix pack -R -S /emacsbin=bin emacs-no-x

Yes, thanks!

I like the way this reminds me of another aspect of the philosophy where
data and code are not separated. One is (or can be) the other, and which
"guix" binary (or script) is used matters.

Thanks again, and best,
