Package: flash-kernel Version: 3.72 Severity: normal Dear Maintainer,
when a Linux kernel is installed flash-kernel creates a dtb backup file. This file is not removed when the Linux kernel is remove. E.g. sudo apt-get remove linux-image-4.8.0-1-armmp left file /boot/dtbs/4.8.0-1-armmp/imx6q-wandboard-revb1.dtb.bak As it is flash-kernel that creates both the /boot/dtbs/$version/$model.dtb as well as the /boot/dtbs/$version/$model.dtb.bak files it should also take care of removing them fully. The .bak file should not be created on the first install of a Linux kernel.
