@maber01 said in How to edit ofono.override?:

@lduboeuf Your instructions for Xenial worked perfectly.

It was necessary to:
sudo touch /userdata/.writable_image
sudo touch /userdata/.writable_device_image
and reboot.

I can see that creating those two files means that the /dev/loop0 device is mounted read/write at boot time which means it is already writable when the ofono.override file is bind mounted.

BTW, can you point me at the documentation about those two files?

I'm afraid there is not. This comes from Telegram discussions
