Space issue on boot made Orange Pi3 board unbootable

[AZ8]

Issue:

1. I have Armbian 22.05 installed on emmc

2. I have run apt upgrade

3. During the process, I got an error due stated that no space on /boot

4. I have tried to reboot but no sign that board starting

5. I have burn SD, load from SD, copy SD boot to emmc boot and than can boot from emmc again

 

The main question is how to prevent this issue in future? How to clean-up /boot from obsolete kernels and avoid space issue?

This problem was mitigated this way
https://github.com/armbian/build/commit/4a689f8b89bca4ecc60a5c24cd8f9beee73bbec9

but perhaps its not enough?
