LPI Linux Certification/Kernel runtime management and troubleshooting

Detailed Objectives (201.3)

(LPIC-2 Version 4.5)

Weight: 4

Description: Candidates should be able to manage and/or query a 2.6.x, 3.x or 4.x kernel and its loadable modules. Candidates should be able to identify and correct common boot and run time issues. Candidates should understand device detection and management using udev. This objective includes troubleshooting udev rules.

Key Knowledge Areas:

Use command-line utilities to get information about the currently running kernel and kernel modules
Manually load and unload kernel modules
Determine when modules can be unloaded
Determine what parameters a module accepts
Configure the system to load modules by names other than their file name.
/proc filesystem
Content of /, /boot/, and /lib/modules/
Tools and utilities to analyze information about the available hardware
