你们有nonetwork这个东西吗？

正在学习gentoo的系统启动，

发现自己/etc/runlevels下面有一个nonetwork，感激很奇怪，应该不是我自己添加的，难道是系统的default setting？

> ls -l
total 16
drwxr-xr-x 2 root root 4096 2009-11-26 09:35 boot
drwxr-xr-x 2 root root 4096 2009-12-03 18:26 default
drwxr-xr-x 2 root root 4096 2009-11-26 09:35 nonetwork
drwxr-xr-x 2 root root 4096 2009-11-26 09:35 single
> pwd
/etc/runlevels
> ls nonetwork/
local
> ls default/
hald  iptables  local  net.eth0  netmount  ntpd  syslog-ng

你们有这个启动级别吗？

从时间上看应该不是我自己添加的。

What is a runlevel?

You have seen that init uses a numbering scheme to decide what runlevel it should activate. A runlevel is a state in which your system is running and contains a collection of scripts (runlevel scripts or initscripts) that must be executed when you enter or leave a runlevel.

In Gentoo, there are seven runlevels defined: three internal runlevels, and four user-defined runlevels. The internal runlevels are called sysinit, shutdown and reboot and do exactly what their names imply: initialize the system, powering off the system and rebooting the system.

The user-defined runlevels are those with an accompanying /etc/runlevels subdirectory: boot, default, nonetwork and single. The boot runlevel starts all system-necessary services which all other runlevels use. The remaining three runlevels differ in what services they start: default is used for day-to-day operations, nonetwork is used in case no network connectivity is required, and single is used when you need to fix the system.
