we are currently deploying info-beamer for an event and have encountered some issues with setting up new devices.
the installer boots, then throws lots of errors, the first one being "can’t unmount /sd, device or resource busy’.
we tried different sd cards, different pis, different images (install.img.gz, custom install.zip, install.zip).
the issue does NOT appear when using an older install image.
the issue did only appear on pi1 and pi zero w. a pi3 was successfully installed using the current image.
