Hello list, I am trying to create an environment where you can't run my binaries on your box and I can't run your binaries on my system (x86 platform). For that, I have modified the system calls table (i.e everything is offset by 5). All the files that need to be re-generated, have been. I ran make buildworld then make kernel. I don't run make installworld because it will not complete (modified libc.so.6). So, just before I reboot, I cp my newly built libc.so.6 from /usr/obj/../lib to /lib/. then power off the box. When it comes back, it panics in kern/kern_exit.c with "Going nowhere without my init!" How can I make this work? Is my initial objective even possible? I think the correct approach would be to have a cpu that no else in the world has, any in between solution.? Thank you for reading, Jerry
