CRUX is a lightweight, i686-optimized GNU/Linux distribution targeted at experienced GNU/Linux users and delivered by a tar.gz-based package system with BSD-style initscripts. It also utilizes a ports system to install and upgrade applications.[2] The current release is 2.7.

Although crux is the Latin word for "cross," the choice of the name "CRUX" itself has no meaning. Per Lidén created it for "sounding cool", using an ending "-X" to evoke Linux and Unix.[3]



CRUX, unlike many other GNU/Linux distributions, doesn't include a GUI installation program. Instead, the user boots the kernel stored on either a CD or diskette; partitions the hard disk drive(s) to which the operating system will be installed (using a program such as fdisk or cfdisk); creates the appropriate file systems on the various partitions; mounts the CD or NFS share along with the partitions made previously for use by the package installation script; compiles a new kernel; and installs a bootloader, all via shell commands.[4][5]

Package Management

CRUX implements an infrastructure similar to that of BSD-based operating systems for package management. Packages consist of a makefile, any patches required to adjust the program to work, md5sum hashes used to verify the integrity of the downloaded files, a footprint file listing the files to be included in the packages, and the package source archived in tar.gz format. These files are downloaded from a CRUX software repository, compiled, and installed using the prt-get frontend to pkgutils.[1]
