Device names change whenever the BIOS boots, that's *everytime* you start  
your computer. If you have more than one hard drive and many thumb drives,  
you can easily see that. Just remove one or more thumb drives and restart,  
you'll see the device names change. Sometimes they change without you  
doing anything.

to list just 2.

So I don't see that as being more persistent than UUID or LABEL. This list  
is referred to by others and is searched when googled, so I hope we can  
provide correct information and if we are not too sure, we should state so.

While it's true that you can always follow your own way, regardless of any  
merit or lack of it, it is always bad advise and unethical if it is  
followed by wrong information. I have said before I don't dislike Karl  
because he's not a deliberately bad person, but the wrong information he  
provides on a technical list like this cannot allowed, and I hope it will  
not be repeated. Whenever someone provides wrong information, someone else  
has to correct it and that's ...tiresome.
