 Gila is a Rust microkernel OS, inspired by microkernel projects such as seL4 and Redox. I aim to implement multitasking, userspace drivers, IPC, and sandboxing. I do not aim to make it POSIX-compatible, but it will likely end up sharing many features with POSIX operating systems. Its design philosophy is focused around simplicity, isolation, modularity, and minimal privilege.
