Linux distributions using musl

• sabotage - experimental Linux distribution based on busybox and musl.
  • About 700 packages including X11, LXDE, alsa, SDL, C++.
  • Supports i386, x86_64, arm, mips, powerpc
  • Uses lightweight replacements for netlink, pkg-config, and gettext
  • Optimized for build speed and small binary size
  • Per-package directories following stow/gobolinux spirit
• bootstrap-linux - consists only of a minimal set of packages that can be crosscompiled. kernel, toolchain, busybox.
• LightCube OS - for now there are only scripts to bootstrap a working environment with musl. This environment will be used to build out a full server-centric distribution with a centralized package repository.
• Snowflake
  • Includes only of a minimal set of packages that can be crosscompiled. (Kernel, toolchain, busybox, gawk, make and sed)
  • Uses pkgsrc for additional packages, so supports thousands of packages
  • Mainly a platform for testing usrview, a system for per-process views of /usr, for very fine-grained control of package management.
• Embedded Linux From Scratch - a fork of CLFS embedded using musl libc
  • 2013-09-28 Updated to correct name of toolchain used
  • 2013-09-14 Updated to musl-0.9.13. Supports *-*-musl* toolchains.
• Cross Linux From Scratch - CLFS uses musl since 16.10.2013 (Announcement)
• morpheus - suckless linux distro
• Bedrock Linux - as of version 1.0alpha4
• Alpine Linux - based on musl since the 3.0 release.
• Void Linux provides official musl based images.
• Exherbo has an x86_64 musl stage.
• oasis - statically linked linux distribution based on musl and other lightweight components.
• JanusLinux - Fast and mini Linux distribution which uses musl libc and busybox userland tools.

Linux distros that plan to switch to musl

• Aboriginal - next major release will be based on musl
• Dragora release based on musl is in the works since 2012. README, BOOTSTRAPPING
