This is a quite intrusive change. In addition to the already reserved runlevels 0 and 6, halt and reboot, respectively, this patch reserves runlevel 1 as *no networking*, like the traditional SysV init did. One of the reasons for this change is the new 'single' user mode, introduced earlier. Most users when entering 'S' or 'single' on the kernel cmdline expect the single user mode (runlevel 1) to be without networking. This leaves 2, 3, 4, 5, and 7, 8, 9 as fully user-configurable runlevels with networking. Of course, networking can still be enabled in runlevel 1 using ifconfig or ifupdown, or change runlevel.
