On a regular base, people ask questions with no other possible answer then:
No, that can't be done, because...
Mostly, this is because of a lack of technical understanding of OP, or because people exactly want to apply howcopy the behaviour of another OS worked. In these situations, the best possible answer(s) explain why it is not possible and suggests one or more alternative solutions, if available.
My suggestion in such cases is to consider accepting nevertheless, ifIf an answer convinces you are convincedthat what you asked for is impossible. It makes it more attractive to answer this kind of questions. For the rep? No way. I'd rather answer a question with a single upvote and an optional acceptance, than with four upvotes"beyond reasonable doubt", but you know there is no wayand it is accepted without giving OP exactly whatexplains very well why, my suggestion is requestedto consider accepting nevertheless.
###Why is that?
To me, the confirmation that an answer is the best possibleWe don't always get what can be done to OP's situation is more important than the reputation. It is the confirmation of the quality of an answer, be it subjective to OP's point of viewwe want. I am pretty sure I amThat does not mean the only one in that.
My suggestion therefore is:
Please consider accepting an answer, if it explains well why what you asked for is impossibleanswer explaining why cannot be accepted.
