Starnix

Starnix is a runner that allows unmodified Linux programs to run on a Fuchsia system. Linux programs on Fuchsia are run in a user-space process whose system interface is compatible with the Linux ABI (application binary interface). Instead of using the Linux kernel to implement this interface, Fuchsia implements the interface in a Fuchsia user-space program called Starnix. Starnix then serves as a compatibility layer that translates requests (syscalls) from Linux programs to the appropriate Fuchsia subsystems.
