Thanks to David's help[1], I realized that the non-filtering of the installation device was causing some of the (uuid->string #f) issues users were experimenting. With this commit: 154a4e046281c28e39b5016e965d3d937a2ea4a1, I improved the install device detection by removing the device with the default Guix System image ISO label. Now this is fragile and won't work if the ISO label is modified like in your use-case. I cannot find another reliable way to detect the installation device in the "non-install-devices" procedure. Do you have any better idea? Thanks, Mathieu [1]: https://issues.guix.gnu.org/44872
