I generated an installer for myself from 5d4ad8e1be6d60c38577e2f3d92cc5642b12eff0 + Miguel's patch (I think unrelated to this bug) here https://paste.debian.net/plain/1167398
After the install completed I pulled out the USB as per instruction on the screen, and pressed the Reboot button. The system then Kernel panic with the following messages:

Sorry I don't have it in textual form.

Is the installed system functional? The kernel panic may come from thefact that the installation support was removed while still needed.
In that case, we could stop advising users to remove the installationdevice before rebooting.
Thanks,
Mathieu

Yes the system was functional. From memory, other distro installers recommend removingthe device and rebooting too. So its curious that Guix somehow has an issue with it.Although this is only one data point. I'd like other people to test it to be sure.

This panic says that PID 1 was terminated by signal 7 (SIGBUS), which isa bit alarming.

Did you remove the device right after the “installation complete”message?
Mathieu, are there other file system operations happening beyond that?
Thanks,Ludo’.

Not really: you're ripping out the root file system while the full system is happily running, then initiating a graceful shutdown sequence that's going to try to read from disc. No distro will survive that.
Some bad installers pretend to. After all: the persistent target device is safely unmounted; let's quietly hard-reset the system!
What I've seen the better ones do is display the ‘plz remove USB’ message very late in the shutdown sequence, when it's actually safe to do so.
Kind regards,
