Linux distributions using musl

  • Per-package directories using qi (an own package manager) and graft following the GNU stow’s spirit.
  • /usr merge, offering compatibility with the Filesystem Hierarchy Standard (FHS).
  • Uses sysvinit combined with perp for the supervision of critical services.

  • 2013-09-14 Updated to musl-0.9.13. Supports *-*-musl* toolchains.
• Exherbo has an x86_64 musl stage.

• morpheus - suckless linux distro
• oasis - statically linked linux distribution based on musl and other lightweight components.
• 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
• 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.
• solyste - statically linked linux distribution targetting embedded hardware and various architectures
• Talos - A modern Linux distribution for Kubernetes.
• TAZ - a Gentoo-based livecd/livedvd
• Vanilla - A radically different, new, simple, customizable Linux distribution based on musl, busybox using LLVM/Clang as toolchain.
• Void Linux provides official musl based images.

Linux distros shipping musl as an optional package

• Arch Linux
• Chromebrew provides an official musl package.
• Debian package is available.
• Fedora package is available starting with Fedora 30.
• Ubuntu package is included in the universe section of the repository starting with Ubuntu 14.04 Trusty Tahr. There is also a PPA available (ppa:bortis/musl) for Saucy Salamander.
• openadk Embedded Linux buildsystem, musl can be selected as the libc of the system.
• OpenWrt packages musl and uses musl as default libc except for mips64 since r45995.
• Yocto - OpenEmbeeded based Yocto Project supports generated embedded Linux distributions based on musl C library
  • Set TCLIBC = “musl” to switch default C library to musl for building embedded linux platforms
