Alpine Linux is a Independent-family Linux distribution based on Independent. Ultra-compact, security-oriented Linux based on musl libc and BusyBox powering the container world.
Strengths: Base root image is only ~5MB (powers majority of Docker containers); apk-tools installs packages in fractions of a second; Proactive security: built with stack smashing protection (SSP). Trade-offs: musl libc can be incompatible with proprietary closed-source glibc binaries (e.g. Steam, proprietary games).
