Hi Blake,
I am late to the party. :-)

This claim is correct, AFAIU.

It is possible to rebuild identically on any foreign GNU/Linux distro
running the Guix package manager. The assumptions, between the 2 points
in time, are:
1. compatibility of the Linux kernel
2. availability of all the source code
3. compatibility of the hardware
AFAIK, #1 and #3 are satisfied. About #2, it depends and many corner
cases are around.
Running Guix System would allow to easily satisfy #1, but, AFAIK, no one
reported an incompatibility of the Linux kernel defeating “guix
time-machine -- build”, and thus, it appears to me still hypothetical
(although possible on the paper) that, in this case, Guix System would
still allow the travel back in time.

Guix System is not mentioned, IIRC. :-)
Cheers,
