Analysis of the Ext2fs structure

Published on 1994, by Louis-Dominique Dubeau, ©Louis-Dominique Dubeau.

This document has been written by Louis-Dominique Dubeau. It contains an analysis of the structure of the Second Extended File System and is based on a study of the Linux kernel source files. This document does not contain specifications written by the Ext2fs development team. Ext2fs was designed by Rémy Card as an extensible and powerful file system for Linux. It is also the most successful file system so far in the Linux community.

Filesystem Hierarchy Standard

Published on 2001, by Daniel Quinlan and Paul "Rusty" Russell, ©BLFS Development Team.

This standard consists of a set of requirements and guidelines for file and directory placement under UNIX-like operating systems. The guidelines are intended to support interoperability of applications, system administration tools, development tools, and scripts as well as greater uniformity of documentation for these systems.

Linux Devfs (Device File System) FAQ

Published on , by Richard Gooch, ©Richard Gooch.

Devfs is an alternative to "real" character and block special devices on your root filesystem. Kernel device drivers can register devices by name rather than major and minor numbers. These devices will appear in devfs automatically, with whatever default ownership and protection the driver specified. A daemon (devfsd) can be used to override these defaults. Devfs has been in the kernel since 2.3.46.

Overview of the Virtual File System

Published on 1999-07-05, by Richard Gooch, ©Richard Gooch.

The Virtual File System (otherwise known as the Virtual Filesystem Switch) is the software layer in the kernel that provides the filesystem interface to userspace programmes. It also provides an abstraction within the kernel which allows different filesystem implementations to co-exist.

Use the /proc filesystem to get a handle on your system

Published on May 14, 2003, by Graham White, ©IBM developerWorks.

The /proc filesystem is one of Linux's great features, and this article gives you a thorough grounding in some of its most useful aspects. With it, you can administer many details of the operating system without ever having to shut down and reboot the machine, which is a boon for those who need to keep their systems as available as possible.

Virtual Filesystem: Building A Linux Filesystem From An Ordinary File

Published on 2004-09-09, by Mike Chirico, ©Mike Chirico.

You can take a disk file, format it as ext2, ext3, or reiser filesystem and then mount it, just like a physical drive. Yes, it then possible to read and write files to this newly mounted device. You can also copy the complete filesystem, since it is just a file, to another computer. If security is an issue, read on. This article will show you how to encrypt the filesystem, and mount it with ACL (Access Control Lists), which give you rights beyond the traditional read (r) write (w) and execute (x) for the 3 user groups file, owner and other.
