Hello, In Linux, we can change the run level by writing into /dev/initctl. I trying to look for the code handling that device, but "grep -r initctl" doesnt show anything useful (??) That is very odd to me. Could anybody please tell me where should I look into for that /dev/initctl? Thank you a lot, NAH -- Kernelnewbies: Help each other learn about the Linux kernel.
