The question _Should an answer like remove Ubuntu and install Slackware be flagged?_ arose myself while answering [_Let's not do “I don't know how to fix your problem, so just reinstall"_](http://meta.askubuntu.com/questions/11710/lets-not-do-i-dont-know-how-to-fix-your-problem-so-just-reinstall), so I decided to ask it as a separate question.

I have searched for similar questions and found this one: [_Should I flag answers which only suggest “install a different OS”?_](http://meta.askubuntu.com/questions/3163/should-i-flag-answers-which-only-suggest-install-a-different-os) (which is quite the same question indeed), but (1) it did not attract much attention and (2) it is 2 years old, so community opinion may have changed since then (that's why I'm asking it again instead of resurrecting the old one).

The opinion I got after reading it is "Don't flag, it is a legit answer" (though it derived to _"[...] install a different desktop environment"_).

Additionally, [questions about unofficial derivatives are close to the thin off-topic line](http://meta.askubuntu.com/questions/684/linux-mint-and-other-unofficial-derivatives-on-topic).

So, recalling, **_should an answer like remove Ubuntu and install (insert distro here) be flagged_** provided it has been proven it solves (or may solve) the problem and the cause is bound to be Ubuntu-specific?
