FreeBSD File System Structure
The Unix File System or UFS file system is straight forward. Here is a screen shot of the root file system:
As you can see we have a variety of directories in root. This will go over a few of the main directories and files.
The first directory I am going to look at is /etc/. This directory hold the main FreeBSD system configuration files end users will edit.
- rc.conf is one of the most important and edited files. This file holds the hostname, IP information, applications to start on boot and any flags associated with them. See below:
- fstab shows what partitions are mounted to what device
- resolv.conf hold what DNS servers to do lookup on
