Hello everyone,

Edgar,

that's exactly what I implemented the past week. I needed to simulate a
proprietary driver from a syscall point of view.

I added hooks for syscalls with basic priorities.

Here a few patch (it's a work in progress).

I'm also interrested in splitting the big sys.call.c (~6k lines) using
theses hooks.

Regards,
