Hi Thomas,
Thanks for the quick and insightful reply!

OK.

I’ve thought about this but that seem highly unlikely at this point.

You could install Guix on top of your distro following the instructions
at
<https://www.gnu.org/software/guix/manual/en/html_node/Binary-Installation.html>.
Then you would need to run “guix pull” to get a current Guix (0.15.0
itself didn’t have this bug.) And finally, run:
guix system disk-image --file-system-type=iso9660 \
-s i686-linux \
~/.config/guix/current/share/guile/site/2.2/gnu/system/install.scm
(This command works on an x86_64 machine.)
The result will be an ISO that’s corrupt.

Something’s fishy, and Xorriso is sorry. :-)
Let me know if I can provide more info.
In the meantime I’ll see if I can build the image from x86_64 instead.

For reproducibility purposes we set timestamps and related things to the
Epoch. This pseudo-UUID/timestamps is actually derived from the config
of the operating system in the image. It’s expected. :-)
Thank you!
