Toybox vs BusyBox
summary
Project history and hard numbers: Toybox becomes Android’s userspace in 2015 and is approaching a 1.0 release, after forking from BusyBox over licensing and maintainability concerns. Goals are tiny, auditable toolchain and self-hosting Android builds using a 509-line make_root script and a reimplemented shell targeted at 3–3.5k C lines (versus ash at ~14k). Previous work replaces ~20 GNU packages with one <1MB package and a seven-package system that can rebuild itself; GPL enforcement on BusyBox adds almost no upstream code. Zero-clause BSD (zero BSD) is used as a public-domain equivalent.
