Alpine Linux

Alpine describes itself as a security-oriented, lightweight Linux distribution for people who value security, simplicity and resource efficiency. It uses musl libc and OpenRC instead of glibc and systemd, and its own package manager, apk.

That combination is why it shows up so often as a container base image and on small edge devices: the base system is small and the package tooling is fast.

Watch out for: musl differs from glibc, so some prebuilt binaries (especially proprietary ones) will not run without recompiling or a compatibility layer.
