*shrug*. I just didn't argue when I discovered that that's the way debian
worked. Coming from RedHat and others before that, I found it a touch

As I pointed out, it's really a matter of "run X or not"...

I log in locally every now and then - that doesn't require X...

Yes, but not necessarily an X console. Text console and serial console
have been sufficient for the last too many years.... And ATM I'd still
consider myself as "doing something wrong" installing X on those things :)

Runlevel 1 is slightly different in ways I don't quite understand to
Single user mode under different unices. In particular, I /think/ it might
have been Solaris which brings network up in that - but I'm REALLY sketchy
on that. Runlevels are what you make of them :)
