How Linux Works: What Every Superuser Should Know
4.2 A Glance at /etc
Most configuration files on a Linux system are in /etc , and because there are so many packages on a Unix system, /etc accumulates files quickly. This makes it hard to see what actually matters to a running system.
In previous chapters, you saw files like inittab and fstab for booting the system. Table 4-1 identifies those and other critical configuration files and where they are discussed in the book.
