Review: Needs Information

Super, thanks for this, Steve.

But is this a workaround? The original bug notes "One possibility is that this is a regression due to wrong behavior of losetup -P returning from the kernel before the devices are settled. If so, this must be a regression in the kernel or systemd since it doesn't line up with the change in util-linux." If this is a regression, then I don't think we should close that bug with this change, should we?

I mean, sure, we could ignored the blkid call as it's there for debugging purposes but ideally we should be looking at why this fails, right?

Either way, I am +1 on landing this for now but not sure if it's appropriate or technically correct to close the bug with this fix. :)
