Thanks!

There is no proper use for it it just gives you more flexibility in your setup. It could be, for example, a runlevel for production applications to be running with them being stopped on runlevel 3.

well, I know you're no fan of Slackware

Slackware uses runlevel 4 to run the X-server.

In fact the definition of runlevels depends on the distribution. With the highly configurable distributions (for example Gentoo) you'll more or less define your own runlevels.

As an example you can define a special runlevel for a laptop which is in battery-mode and adapt it for less energy-consumption.
