Hello Richard; yours is a good answer. Let me add:

Note that “guix time-machine … -- install” or “guix time-machine … --
build” can be used for individual packages. So repeated time-machine to
each package’s commit can reproduce the environment (have not tested it,
but should be true).
guix time-machine can also take a channel description file instead
of a commit, if we are talking about other channels.
Also to comment on Mauritz’ question, the @ syntax of guile@2.2.7 has
nothing to do with reproducibility. Everybody understood correctly that
by A@old, A from an old Guix commit was your intended meaning; I want to
clarify this for future readers.

Florian
