In Linux? I mean, runlevel 3 was multi-user text mode as far back as Sun OS - I can remember putting things into 3, because X would while () { crash respawn }
Originally runlevel 2 was multiuser, 3 was multiuser with networking and network daemons. Without serial terminals, that wouldn't make a lot of sense...
On System V and Solaris runlevel 5 is halt so you might get a nasty surprise if you were expecting X11!
I think adding 5 for X was a Linux kludge. And in the original sysV design, I believe each runlevel was executed in sequence up and down. That is, everything started in runlevel 1 and 2 started on the way to 3 and could be sequenced properly that way instead of jumping directly to 3 or 5 and having to have everything specified to start there.
