hi @11iy ,

I can see this PR unfortunately breaks the system.
I would suggest to remove the modifications of the files in '/bin/'

Furthermore, the intention of the task is to add a function that is able to detect the type. Therefore a test case is not sufficient.

Thanks for the patch @11iy and sorry for the delay - as discussed offline, I will help to clean this up and move this to staging once its mostly operational.
