# 5.3 Kernel Parameters(内核参数) When running the Linux kernel, the boot loader passes in a set of text-based kernel parameters that tell the kernel how it should start. The parameters specify many different types of behavior, such as the amount of diagnostic output the kernel should produce...
Another way is to use Mainline toremove old kernels on Ubuntu. To do that, click the previously installed (or any older) kernel version and chooseUninstallon the right-hand side. Conclusion This guide showed how to update the Linux kernel using several different methods. We also showed how t...
In addition to the applet, there are a few tools that you can use to query and control NetworkManager from your shell. For a very quick summary of your current connection status, use the nm-tool command with no arguments. You’ll get a list of interfaces and configuration parameters. In ...

Chapter 5. How the Linux Kernel Boots(第5章 Linux内核的启动过程) You now know the physical and logical structure of a Linux system, what the kernel is, and how to work with processes. This chapter will teach you how the kernel starts— or boots. In other words, you’ll learn how the...
The first kernel reserves a section of memory that the second kernel uses to boot. Be aware that the memory reserved for the kdump kernel at boot time cannot be used by the standard kernel, which changes the actual minimum memory requirements of Red Hat Enterprise Linux. To compute the actua...
