Comment 2 for bug 1698337

Thanks, we had a report of this in the morning, but this captures that the device isn't there.

Clearly the synchronous option to kpartx isn't all we want it to be. I think a sleep after the call might be the quickest solution here. Or maybe a udevadm settle call ... But maybe that is just a placebo for a sleep.

I'm on a phone so can't propose a change, but I think that will help
