Now when Charlie logs in on console (either Ctrl-Alt-F2 to get to a console or enter runlevel 3 as described earlier), he will be asked which role to log in to.
A runlevel describes the state that your machine will be running in. Sound redundant?
makefile文件runlevel . mk是控制程序,start5 . mk文件和stop5 . mk文件分別是運行級5時啟動和停止服務時的服務依賴描述文件。
Note: if the system appears simply too slow to be bearable, you can exit X-windows by entering runlevel 3.
To test your installation on Ubuntu V7.10, enter runlevel 1 and start GDM as root, preferably with the -nodaemon option.
As an example, if you wanted to remove the yum-updatesd program from runlevel 2, you could simply remove the link /etc/rc.d/rc2.d/S97yum-updatesd.
當更改到一個新的runlevel時,對runlevel文件的更改將被識別。
此文件將提供關於runlevel及在各個runlevel上應當啟動的進程的init信息。
