This Advanced administration tutorial (Part 4) is ideal for those who want to learn about or improve their Linux filesystem-related skills. This tutorial is particularly appropriate for someone who may be serving as the primary sysadmin for the first time, since we cover a lot of low-level issues that all system administrators should know. For many, much of this material will be new, but more experienced Linux users may find this tutorial to be a great way of "rounding out" their important Linux system administration skills and preparing for the next LPI certification level.

If you are new to Linux, we recommend that you complete Part 1: Linux fundamentals, Part 2: Basic administration, and Part 3: Intermediate administration of this tutorial series before continuing.
