There are a number of Linux distros which attempt to strip Linux down to a minimal set of elements that can run on computers with reduced capabilities. Some of them are targetted to old computers. Some are targetted to so-called embedded systems which are built into machinery, vehicles, home appliances, PDAs and mobile phones.

  • Zenwalk, an OS that strives for simplicity. Based on Slackware.
  • OpenEmbedded Not a distribution, but a tool to build lightweight distributions for various architectures, which includes the Zaurus
  • Buildoot A cross compilation framework for building root file system images. A large number of packages are provided to add useful programs. Suited for embedded development.
  • DeliLinux "Desktop Light" Linux. It is a Linux Distribution for old computers, from 486 to Pentium MMX 166 or so on
  • PuppyLinux targetted to older computers and education. They have put up a page describing how they adapted Puppy to an NTAVO low memory system. See the PuppyLinux page for pointers to an active forum on OLPC.
  • BasicLinux targetted to very old computers including 486es
  • FeatherLinux that takes under 128MB of disk space. Minimal requirement for X is 24MB.
  • ucLinux targetted to embedded systems with low memory and no hard drive (like OLPC)
  • Zaurus this is a Linux-based PDA that uses busybox. It is similar to the OLPC except that it has a PDA-size 640x480 screen.
  • Damn Small Linux - less than 50 MB!
  • MenuetOS - An Opensource Assembly Language OS.Fully working at great speed, But there is lack of Applications.Have small footprint.since the size is small it can include in a 1.44floppy along with all applications.
  • SLAX is a small Linux distribution based on Slackware Linux. Boots from USB-Stick or CD-ROM and has many modules to choose from for an individual flavour. Good auto-detection of hardware. Runs on a read-only filesystem, but can be easely transfered on the harddrive, and can then be run from harddrive or loaded in memory.
  • STX Linux STX Linux is a desktop Linux distribution especially targeted to older hardware. It also works quite well on new PC's.
  • Ubuntu Lite is an unofficial derivation of the Ubuntu Linux distribution. It is intened to be used on much weaker hardware than the offical weak hardware distribution Xubuntu and should run on a Pentium 200Mhz with 64MB RAM. A minimum of 50MB hard disk place is required to install and run it.
  • Xubuntu is a complete GNU/Linux based system with an Ubuntu base. It's lighter, and more efficient than Ubuntu with GNOME or KDE, since it uses the Xfce Desktop environment, which makes it ideal for old or low-end machines, as well as thin-client networks.
  • Edubuntu: Linux for Young Human Beings - "Ubuntu" is an ancient African word, meaning "humanity to others". The Edubuntu Linux distribution brings the spirit of Ubuntu to schools, through its customised school environment. The current version of Edubuntu is aimed at classroom use, and future versions of Edubuntu will expand to other educational usage, such as university use.
  • MuLinux, a distribution that runs from a floppy
  • IPCop firewall and network sharing on miminal PC hardware, work with 486, 16MB memory, installable on flash disk (mini 128MB), usb or network boot,28 langs
  • OpenWrt is a distribution for Wireless APs like WRT54G, nice Konfiguration Interface like kernel menuconfig (ncurses?) for build process
  • Trinuxand Ubuntutrinux - a small ramdisk-based distribution especially suited for network monitoring
  • TomsRtBt Toms Root an Boot floppy is a 1.7MB floppy for rescuing purposes. imho not maintained anymore. Uses bz2 compression for kernel
  • GeeXboX CD/USB/PXE bootable distro focusing on multimedia, using mplayer. Based around a linux kernel plus custom patches. Uses uClibc C library and busybox for it's core utilities. Around 22MB in size.
  • TTY Linux: 5-10MB Linux system, runs even on 386's.

Please add other minimal Linux distros to this list. In the end, it is unlikely for OLPC to adopt any one of them but it is quite likely that OLPC will borrow good ideas from some of them, such as the busybox from ucLinux.
