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 the
fact that the installation support was removed while still needed.
In that case, we could stop advising users to remove the installation
device before rebooting.
Thanks,
Mathieu

Yes the system was functional. From memory, other distro installers
recommend removing
the 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 is
a 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’.

Hey,
> Mathieu, are there other file system operations happening beyond that?
The final "sync" call is done just after the user clicks on "Reboot", so
if the flash drive is removed before clicking on "Reboot" I guess things
can go wrong.
I'll see if I can reproduce this issue.
Thanks,
Mathieu

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,
T G-R
