it completes and display "Hello, world!".  Well, the commit 0d371c6 is
one day older than the one you used 9744cc7.


Then, let pull the same faulty version

  guix pull --commit=9744cc7 -p /tmp/new

and re-run the time-machine using '/tmp/new/bin/guix'.  It completes too.


Do not know if it helps.
