On ’Machine-A’, if you run,
machine-A$ guix package --list-generations
then I guess ’glibc’ is not installed in the same transaction
(generation) as all the others.
You can open the internals. :-) For instance, on ’Machine-A’, give a
look at the internal file ’~/.guix-profile/manifest’. You should see
’glibc’ and its provenance (commit) and I bet it is different from the
other provenance.
Other said, the profile on ’Machine-A’ is populated by various states
(revision). I guess glibc is at 2.31 at one state and then become 2.33
at another state. The command “guix package --export-channels” makes
approximation to pick only one state when the profile is composed by
several ones.
Then it becomes hard, nor impossible, to replicate this multi-state
profile on another machine. “Nor impossible” because it is possible to
use inferiors [1] although I would not recommend going this way.

Well, from my point of view, the best practise is:
1. track channels.scm from “guix pull -f channels”
2. track manifest.scm
then
guix time-machine -C channels.scm -- <cmd> -m manifest.scm
works independently of the time and of the machine; or it should be. ;-)
Cheers,
simon
