With a superficial knowledge of the problem domain I can guess that `target` is a string. (Now I have found http://www.freedesktop.org/software/systemd/man/systemd.special.html as a reference). Does it include the ".target" suffix?
But `services`? Many formats are possible. I can guess that it is a list of the above declared Service, but I shouldn't have to guess.
Is `autoyast_profile` a XML string? A list/hash? The whole profile? The part for us? Including the top element?
