While having a seperate kernels partition (/boot) is a good idea, it's easy to forget to mount it when copying kernels across. If it were made unwritable (chmod 000) in the installation process this would not be possible. The permissions of mount points are ignored, so it won't change anything in the case of users who never get it wrong. Reproducible: Always Steps to Reproduce: 1. Compile kernel. 2. Forget to mount boot. 3. Copy kernel across. 4. Reboot. Actual Results: Be confused as to why your "new kernel" isn't working as expected. Expected Results: Feedback that a silly action was being performed.
