In both Slackware 10.0 and Debian {3.1,4.0}, it's possible to 
differentiate the runlevels. Slackware used 4 for X11, and I configured 
Debian to do the same.

You can change the runlevel usage in Debian by invoking, as root, 
update-rc.d with the appropriate parameters. Manipulating the symbolic 
links in /etc/rc?.d/ also works.

Ubuntu is another story. Ubuntu seems to simply ignore the runlevel 
passed in on the kernel command line, so there must be some other way to 
signal to Ubuntu that a non-default runlevel is wanted (at boot time).
