%general-entities; ]> CLFS includes many packages, a number of which might not necessarily be required for a "minimal" system, but still considered very useful. The purpose of this page is to list the reasoning for each package's inclusion in the book. Autoconf The Autoconf package contains programs for producing shell scripts that can automatically configure source code. Automake The Automake package contains programs for generating Makefiles for use with Autoconf. Bash This package contains the Bourne-Again SHell. Binutils This package contains programs for handling object files. The programs in this package are needed for compiling most of the packages in CLFS. Bison Required by several package in CLFS Bzip2 The programs in this package are useful for compressing files to reduce size. They are also needed to uncompress tarballs for many CLFS packages. CLFS-Bootscripts This package contains a number of scripts that run at boottime, performing essential tasks such as mounting/checking filesystems and starting the network interface. CLooG-PPL Used by GCC Coreutils This package contains many basic command-line file-management tools, required for installation of every package in CLFS. DejaGNU This package is needed for the testsuites of several packages, especially GCC and Binutils DHCPCD This package allows for automatic configuration of network interfaces from a DHCP server Diffutils This package contains programs to compare files, and can also be used to create patches. Required by the installation procedures of many CLFS packages. EGLIBC Any dynamically-linked C program (which is nearly everything in CLFS) needs a C library to compile and run. Expect This package is needed for the testsuites for several packages. E2fsprogs The programs in this package are used for the creation and maintenance of ext2/3/4 filesystems. File This package contains a program that determines the type of a given file. It is needed by some CLFS packages. Findutils This package contains programs for finding files based on certain criteria, and optionally performing commands on them. Used by the installation procedures of many CLFS packages. Flex This package contains a tool for generating text scanners. It is used by multiple packages in CLFS Gawk This package contains programs for manipulating text files, using the AWK language. It is used by the installation procedures of many packages in CLFS. Gcc This package contains a C compiler, which is required to compile most of the packages in CLFS. Gettext A tool that allows programmers to easily implement i18n in their programs. It is a required dependency for a number of packages Glib Required for pkg-config GMP Required by GCC Grep Programs for searching for text in files. Required by many packages in CLFS. Groff Required by Man Gzip Useful for compressing files to reduce size. Also needed to uncompress tarballs for many CLFS packages Iana-Etc This package provides the /etc/services and /etc/protocols files. These files map port names to port numbers as well as protocol names to their corresponding numbers. These files are essential for many network based programs to work properly. IProute2 This package contains programs for administering network interfaces. IPutils This package contains several basic network-management tools. Kbd Contains keytable files and keyboard utilities compatible with the Linux kernel. Less A program that lets you view text files one page at a time. Used by Man for displaying manpages. Libee This package contains an event expression library. Libestr This package contains a library for string essentials. Libtool The Libtool package contains the GNU generic library support script. It is used by some CLFS packages. Linux-Headers This package consists of santized headers from the Linux Kernel. These headers are required for Glibc to compile. Linux Kernel The Linux operating system. M4 This package contains a macro processor. It is required by several CLFS packages, including Bison. Make Required for installation of most CLFS packages Man Used for viewing manpages Man-Pages A number of useful manpages, not supplied by other packages MPC Required by GCC MPFR Required by GCC Module-Init-Tools This package contains programs that assist in Ncurses Needed by several packages in CLFS, such as Vim, Bash, and Less Patch Used for applying patches in several CLFS packages Perl The Perl package contains the Practical Extraction and Report Language. It is required by several CLFS packages. Pkg-config Needed by E2fsprogs PPL Used by GCC Procps Provides a number of small, useful utilities that give information about the /proc filesystem. Psmisc Provides more utilties that give information about the /proc filesystem. Readline The Readline library provides a set of functions for use by applications that allow users to edit command lines as they are typed in. This is essential for input in programs like bash to work properly. Rsyslog Rsyslog is an enhanced multi-threaded syslogd that supports multiple backends with very little dependencies. It provides a program that logs various system events into files in /var/log. Sed This package contains a stream editor. It is used in the installation procedures of most CLFS packages. Shadow This package contains programs that assist in the administration of users and groups, and passwords. Sysvinit Sysvinit is the init daemon that the clfs-bootscripts were written to work with. Tar Required to unpack the tar archives in which all CLFS packages are distributed Tcl Needed for the testsuites of several packages Texinfo This package contains programs for viewing, installing and converting info pages. It is used in the installation procedures of many CLFS packages. Udev The Udev package contains programs for dynamic creation of device nodes. Util-linux The Util-linux package contains miscellaneous utility programs. Among them are utilities for handling file systems, consoles, partitions, and messages. It also includes libraries that are required by E2fsprogs. Vim The Vim package contains a text editor. Users may substitute Nano, Joe, Emacs, or whatever other editor they prefer. XZ-Utils Useful for compressing files to reduce size. Also needed to uncompress tarballs for many CLFS packages Zlib The Zlib package contains compression and decompression routines used by some programs.
