Kernel 蒌入完成後, Kernel ?把?行?交斤 init, 而 init ?去坐取 /etc/inittab
中的以下呃列??定 runlevel.
# Default runlevel. (Do not set to 0
or 6)
id:3:initdefault: style="font-weight: bold;">
runlevel 的定柳如下
0 = halt, 晷?
1 = single user mode, ?人使用模式
2 = unused (but configured the same as runlevel 3)
3 = multiuser mode (default Slackware runlevel), 多人使用模式
4 = X11 with KDM/GDM/XDM (session managers), x ?窗使用模式
5 = unused (but configured the same as runlevel 3)
6 = reboot, 重新檫?
以下呃列?第一?被?行
# System initialization (runs when
system boots).
si:S:sysinit:/etc/rc.d/rc.S style="font-style: italic;">
然後再依 runlevel 去找要?行那? shell script
# Script to run when going single
user (runlevel 1).
su:1S:wait:/etc/rc.d/rc.K style="font-style: italic;">
# Script to run when going multi user. style="font-style: italic;">
rc:2345:wait:/etc/rc.d/rc.M style="font-style: italic;">
# What to do at the "Three Finger
Salute".
ca::ctrlaltdel:/sbin/shutdown -t5 -h
now
# Runlevel 0 halts the system. style="font-style: italic;">
l0:0:wait:/etc/rc.d/rc.0 style="font-style: italic;">
# Runlevel 6 reboots the system. style="font-style: italic;">
l6:6:wait:/etc/rc.d/rc.6
# Runlevel 4 used to be for an X window only system, until we discovered
# that it throws init into a loop that keeps your load avg at least 1
all
# the time. Thus, there is now one getty opened on tty6. Hopefully no
one
# will notice. ;^)
# It might not be bad to have one text console anyway, in case something
# happens to X.
x1:4:wait:/etc/rc.d/rc.4
所以如以盍韵的 runlevel ?整?流程如下
