Even when process=1 is started, it still leaves a window when the signal handler setup has not been completed.
Yes, but you can still use kill(pid, 0) to check whether init is ready to receive signals: doublefork a zombie and repeatedly kill it with signal 0. When you get -1 ESRCH, it means init has reapt the zombie, so it's in its reaping loop, and at that point you know it has installed its signal handlers. See http://lists.busybox.net/pipermail/busybox/2017-October/085888.html That's arguably uglier than using abstract sockets, but it can be done without modifying the init code at all. -- Laurent _______________________________________________ busybox mailing list busybox@busybox.net http://lists.busybox.net/mailman/listinfo/busybox
