[Bug] df does not return all drives inside the container

[MauriceNino]

Description of the bug

Drive information is gathered using df, which returns only the root drive / inside the docker container, while it returns all drives on the host.

This should not be the case, because with --privileged, all devices should be available inside the container.

BUT - the device is actually mounted, which can be seen when using ls -la /dev

How to reproduce

Connect to the docker container and run df:

docker container exec -it CONTAINER_NAME /bin/sh -c "df"

And check that it is mounted with:

docker container exec -it CONTAINER_NAME /bin/sh -c "ls -la /dev/DRIVE_NAME"

Additional Context

I have opened a StackOverflow question with a bounty: https://stackoverflow.com/q/72517164/9150652

If the SO question results in no answers, I will create a temporary solution where users have to mount -v /dev/:/mnt/host/ (or something similar) until this really gets resolved.

On Raspberry Pi 4, it also doesn't correctly show storage either.

Hi @CyberiumShadow, thanks for reporting!
Can you post more info in a new issue, please? We already have Raspberry 4's running which show the correct info, so it would be interesting to see the log output, as well as your setup.

Temporarily fixed with volume mounts. If there is a better solution, I will create a new issue for it.
