I have created a synonym proposal on non-root-user because this is where I have the necessary score, but the question would probably be which of the two ones should "survive". non-root-user sounds better that not-root-user to my ears, but the latter has more questions tagged.
I agree with this and would prefer to see non-root-user as the primary tag.

Why bother ?
Too many categories kill the interest of categorizing.
Categorizing out of the possible interaction of possible interested end-users is just : useless (to users).
Therefore : Burn! Burn! Burn!
Which one ?
Not to tell my personal opinion that as soon as, about a purely technical matter, whatever question turns to be what ? Lexical ? Syntactical ? Rhetorical ? matter… Well… please… blame me if I sound vulgar : FTS!
