Would it be possible to use rump kernels with this to get support for the myriad hardware out there from the get-go? Or are QNX-esque microkernels and rump kern

• Animats 8y ago
  Using the drivers from rump kernels with a QNX kernel might work. QNX runs drivers, file systems, and networking in userland. The rump kernel people have those components. The QNX kernel itself does only memory allocation, process management, CPU dispatching, timers, and inter-process messaging. So it's tiny, relatively trouble-free, and has a small attack surface. So if someone implemented a QNX-style microkernel in Rust, file systems and networking could be adapted from rump kernels. Drivers would require more porting. That would be a nice way to get a usable but small OS for embedded and IoT devices. Linux has more than you want in an embedded device.
