Comment 10 for bug 1593379

I might be doing something broken, but it still seems broken to me on Ubuntu 16.04 on Raspberry PI despite having these fixes applied.

Package versions:
systemd: 229-4ubuntu7
udev: 229-4ubuntu7

Could you please take a look if I'm not doing something stupid (I hopefully attached the relevant info):
