Unit 2 discuss
EXT2 was the default file system for Linux until EXT3 came along. EXT2 still is a favored file system for Flash and USB drives due the lack of journaling. Journaling requires more writes to the storage unit and can be slow on these external devices. The Flash and USB drives have a limited number of write cycles.
The Filesystem Hierarchy Standard (FHS) is a reference describing the conventions used for the layout of a UNIX system. It has been made popular by its use in Linux distributions, but it is used by other UNIX variants as well. The Linux Standard Base (LSB) refers to it as a standard. In the FHS all files and directories appear under the root directory "/", even if they are stored on different physical or virtual devices. Note however that some of these directories may or may not be present on a Unix system depending on whether certain subsystems, such as the X Window System, are installed.
The Linux Standard Base (LSB) is a joint project by several Linux distributions under the organizational structure of the Linux Foundation to standardize the software system structure, including the filesystem hierarchy used in the GNU/Linux operating system. When targeting Linux as a platform, application developers want to have some assurance that the code they write on one Linux distribution will run on other Linux distributions without having to go through extra effort. This matches their experiences on other popular platforms, such as Windows or Mac OS X. In addition, application developers want to ensure that the platform as a whole does not diverge. Even if an application works on today's distributions, will it work on tomorrow's? The LSB workgroup has, as its core goal, to address these two concerns. We publish a standard that describes the minimum set of APIs a distribution must support, in consultation with the major distribution vendors. We also provide tests and tools which measure support for the standard, and enable
