Referring to this question: How to enable root login? (and this edit of that question).
There is an added remark in this question which doesn't seem to belong in the the body of a question:
Mod Warning: Running as root is a bad idea - You never need to do it but if you do you can very easily and irreparably destroy your system and your data.
Apart from if you think this remark is needed, the placement and method are off as far as I'm concerned. It's meta-information, and should be at most a comment. It doesn't belong in the question body.
Also, it was removed by the origional poster, and then rolled back: looks like the beginning of a small edit party?
Overall I think that, just like "this is urgent" remarks, that remarks like "this is dangerous" do not belong edited in the question.
I wasn't sure if I needed to make this a meta-thing, but my flag was declined with this note:
your flag comments are probably more appropriate on meta - suggest raise a question there with a link back to this Q.
So here we are:
