My /boot is full! I had left it at the 'default' of 524MB and after all the kernel updates, it is finally full. I would say this is a bug in update-boot, not to trim down /boot old images. So I had to delete the 201 and 202 files out of /boot to install this latest 4.9.34-203. But what about removing the directories: dtb-4.4.34-201.el7.armv7hl dtb-4.4.42-202.el7.armv7hl Can those also just be deleted? thanks
