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 GNU/Linux and Unix.
Arch Linux is a GNU/Linux distribution that, while independent of CRUX, drew inspiration from the minimalist philosophy on which it and other distributions are built.
CRUX, unlike 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.
Tilman Sauerbeck has announced the release of CRUX 2.7, a minimalist Linux distribution designed for intermediate and advanced users: "I'm announcing the release of CRUX 2.7. Release notes: toolchain updates - CRUX 2.7 includes glibc 2.12.1, GCC 4.5.1 and Binutils 2.20.1; Linux kernel 18.104.22.168; X.Org 7.5 and X.Org Server 1.9.0; to save space, all packages shipped with the image are compressed with xz, which requires a new version of pkgutils, a gz compressed package of pkgutils has been placed the /tools subdirectory; besides the usual ISO image, an image suitable for USB thumb drives is available from our download mirrors. New features in pkgutils: in addition to gzip, pkgmk has been enhanced to optionally compress newly built packages with bzip2 or xz; pkgutils can read packages that have been compressed with bzip2 and xz in addition to gzip...."
