Hi Rich,

I am trying to build for Raspberry Pi including "read-only-rootfs" in
my image features. My aim is to have my SD Card read-only and at some
point add a read-write overlay to certain directories. This should
enable my system to boot fresh each time, and have some persistent
storage for user files etc.

However, after building my image I can SSH into the system and issue
"touch test" to create a file in my home directory, then after a
reboot it is still there. That isn't very read-only :)

Am I missing something, or is this working incorrectly?

It sounds like it's working incorrectly. Since meta-raspberrypi constructs the
SD card image using its own custom class I wonder if it has anything to do
with that. Andrei, do you know anything about this?

BTW, are you using sysvinit or systemd in this image?

Cheers,
Paul
