Wohoo it's working. The #rasperrypi zero is fetching the latest images from the #synology NAS when the frame is powered on.
Also found a way to disconnect the gadget from the frame using #configfs. That allows to update the data on the USB drive,disconnect and connect again, so that new content will be displayed without restarting the frame.

Unfortunately, that garbage is userland ABI and we should've said "no" back in 2005. Too late now, so we get to play very ugly games with locking.

Try *ANYTHING* of that sort in new code, and you will really regret it. Just ask yourself - what could a BOFH do to me and do I want to find it out first-hand?

AV, a thoroughly annoyed bastard. */
