Yes, but you can also search for a label.  I also would like to make
it possible to search for an UUID.

Why is this a problem?

I think that's something positive and not a problem, right? ;-)

That depends on the problems you want to solve.  I prefer to talk
about problems and how to solve them.  Perhaps there are more elegant
fixes, who knows. :-)

I will think about all this.  I have something more elegant in mind
that will solve this.  Although I still don't see the problem. ;-)

This depends on how something in scripting will be implemented.  I
want to give it more thought before bringing it up.

This is only a problem when using search to look for files.  I assume
this is what you are talking about?  Thus you can not determine which
disk search will find?

Adding the capability to use UUIDs can solve most of the problems you
encounter.  The (existing) label feature can also be used.  Perhaps
other techniques can be added as well.
