I have read this artitle:kodi - Edit read-only file (in /etc/init.d) or override settings file from /storage directory - Raspberry Pi Stack Exchange
And after I copy SYSTEM, uncompress it, modify it and finally compress it to use again, I just could not boot the LibreELEC. It reads unable to mount /boot/SYSTEM.
So why would that happen? What's wrong?
I just want to modify several files, so I don't want to build the whole image from scratch.
Any easy way to modify the read-only image?
Please tell me, thank you.
