Did you capture the backtrace from /tmp/last-installer-error?  That
would be great.

I don’t understand; what is this telling us?

I’ll run the installer tests on ISO9660, with the patch applied, and if
everything goes well, we can use it (and roll an RC2, I guess.)

Could we come up with a udev rule or a modprobe.d snippet so that this
happens automatically?

I found things like:

  https://bbs.archlinux.org/viewtopic.php?id=165480

Or should we give up on v86d like Gentoo:

  https://wiki.gentoo.org/wiki/Uvesafb

?

(Perhaps this is best discussed in a specific issue on bug-guix.)

Thanks for the detailed report, as always!
