Thanks for digging into this and finding your root cause!

I'm really wondering what is causing this additional \r on that variable compared to a standard installation, with multiple kernels and initrds, which doesn't get this \r. Do you have any specific grub configuration in /etc/default/grub* or anything in /boot which can lead to this? Could be mirror-related, where grub_probe --target device returns this \r. What's the value of $initrd_device?

The reason is that I would like to add this case to the testsuite to ensure we don't regress it in the future and so, trying to find the root cause (we can mock grub_probe in our testsuite to return what you got exactly).
