@Eric-Johnson I don’t want to take over this topic as it’s been mainly you and @Quazz who figured this one out! But I did add the changes and would be thankful if you’d give it a try in your setup. @Cheetah2003 and all the others are welcome too!

Maybe a combination of udev and sfdisk - very likely one or both are involved.
