That simplifies things :) I tested v0.3 and besides some glitches due to my system everything worked fine. I'm using fgetty (yeah, freeing a couple more kb might not be worth using it, but I tried it some time ago and kept it) and it complains about file descriptor 3 when I try to log in. Aparently (haven't checked the fgetty code) it uses file descriptor 3 for internal communication of some sort and that would be sinit's sigfd. I added a line to spawn() to close sigfd in the first child (if sigfd >= 0) and I could log in again. Speaking of children, I think you could drop the double fork in spawn now, since pid 1 already waits for children. And since sinit uses Linux specific code anyway you might consider calling reboot(0) to tell the kernel to send SIGINT to pid 1 on ctrl-alt-del. -- Eckehard Berns
