Which means that the delay in the "with-delay-device-in-use?" procedure
is probably not high enough.

Here is an attached patch to bump it from 16 to 96 seconds. I also
uploaded an image built on top of of the version-1.4.0 with this patch
if you are up for a retry :), you can download it this way:

--8<---------------cut here---------------start------------->8---
wget https://othacehe.org/files/installer.iso
--8<---------------cut here---------------end--------------->8---

Thanks,

Mathieu
