Fix inconsistent handling of binary variable. get_binary_variable() stores the result into a global variable we pass later on as argument to FTLinstall() and define a local variable with the same name. This is fixed by only using the globa variable in all places not. This is still not a very elegant solution but it is also not subject of the current PR.
