    Yes, that is right ... my fault.

    Yes surely, I did a lot of --exclude=/mnt --exclude=/dev ... that was not the
    problem.

    What I do not understand is:
    I am in directory /home/me/TAR_EXAMPLE
    Now I want to tar directory /tmp for example then I do

    tar cvzf temp.test.tar.gz /tmp

    Afterwards I receive in the directory /home/me/TAR_EXAMPLE the archive
    temp.test.tar.gz which can be untared without any problems.

    But ... trying to do

    tar cvzf root.test.tar.gz / --exclude=home --exclude=/dev

    I receive the archive root.test.tar.gz in directory /home/me/TAR_EXAMPLE
    but trying to untar it gives me the mkdir-error-message.

    Why is tar not processing the / directory like any other directory and why is
    it adding a / when tar xvzf cannot untar it?

    So the conclusion would be that trying to tar the / directory I have to cd
    into that directory to make it working while with any other directory I can
    start the tar-process from where ever I want?
