but they contain the word warning. A warning usually means something is wrong but the program will try to continue running anyway. To fix a problem noted in a warning message, you may have to hunt down a process and kill it before doing anything else. (You’ll learn about listing and...
A system spends most of its time in a single runlevel, but when you shut the machine down, init switches to a different runlevel in order to terminate the system services in an orderly fashion and to tell the kernel to stop 在Linux系统上的任何时刻,都会运行一定的基本进程(如crond和udevd)。
