Run levels 2 and 3 vary by distro in their interpretation.

I'm not positive, but I think that RH based distros might consider 3 to be
undefined (as is 4). What is considered as multi-user on RH is 2, while on
debian it's 3. Or something like that.

Can someone please explain in an understandable way what's what on which?
