Alpine Linux

Alpine Linux is a Linux distribution "designed for power users who appreciate security, simplicity and resource efficiency". It uses musl, BusyBox, and OpenRC instead of glibc, GNU Core Utilities, and systemd, respectively. This makes Alpine one of the few Linux distributions not to be based on systemd. For security, Alpine compiles all user-space binaries as position-independent executables with stack-smashing protection. Because of its small size and rapid startup, it is commonly used in containers providing quick boot-up times, on virtual machines (e.g., OS-level virtualization) as well as on real hardware in embedded devices, such as routers, servers and NAS.
