AFAIR these should be made accessible within the VM (directory /exchange).

Use this copy to start the desktop (instead of the system one) as
this copy can be adjusted and e.g. debug messages be added or commands
by run via `strace`.

Not sure what I used this for. I assume this is used for quickly
running tests for `kwin` without actually rebuilding the package
every time.

This is just to pass my knowledge and processing to somebody who wants to
work in Plasma for Guix.

This reverts commit c65ccb5d7dc8511755511877bab2a336f4634562.

Try if this is necessarry.

Commitd to save the work.
