Thanks, diffing those, I can see on disco, we see this kernel/udev message.

And I can see that is is now related to _multipath_ package being present in the disco images, but not in bionic...

Let's add a multipath task here; somehow due to the multipath package which adds new udev rules, it runs different commands to query the ID_SERIAL value from devices...
