Re: shutdown computer after the halt command
Allow me to split hairs here. I was taught sync;sync;sync;halt. One for the father, one for the son, one for the holy spirit. This, of course, in the days when I/O was slow enough that sync didn't have time to finish before the halt, so doing it three times ensured your file system shut down cleanly.

It's quite easy to see you're wrong, just follow the steps I outlined above. If you are correct, reboot(8) should print things like: Stopping sshd. to the console. It doesn't and shutdown(8) does so the proof is right there. The reboot man page only hints at it though unfortunately which caused my initial confusion(in addition to the permissions mismatch between the two). Normally, the shutdown(8) utility is used when the system needs to be halted or restarted, giving users advance warning of their impending doom and cleanly terminating specific programs. You can also reference init.c if you still think you're correct. In addition, please read carefully through this thread and then examine your arguments vs what is reality and then we can all be on the same page. http://lists.freebsd.org/pipermail/freebsd-stable/2010-December/060519.html -- Adam Vande More ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org
Re: shutdown computer after the halt command
It's quite easy to see you're wrong, just follow the steps I outlined above. If you are correct, reboot(8) should print things like: Stopping sshd. to the console. Sigh. I shut down my FreeBSD 8.1 laptop all the time with halt -p, and I can assure you it prints all those messages. You can also reference init.c if you still think you're correct. No thanks, I've already read the man page for init, including this paragraph: When shutting down the machine, init will try to run the /etc/rc.shutdown script. This script can be used to cleanly terminate specific programs such as innd (the InterNetNews server). If this script does not termi- nate within 120 seconds, init will terminate it. The timeout can be con- figured via the sysctl(8) variable kern.init_shutdown_timeout. If you're unfamiliar with rc.shutdown, it also has a man page. Perhaps your copy of FreeBSD was installed incorrectly, or it's been so long since you tried halt or reboot that you forgot what happened.

Re: shutdown computer after the halt command
Hmmn, I looked at the code and by golly you're right, halt/reboot doesn't poke init. Nonetheless, I really do see a lot of foo stopping messages when I use halt, presumably because the SIGTERM that halt/reboot sends has the same effect (if not the same ordering) as the ones that the various rc.d scripts send. Looks like init 0 would be tidier than halt -p, and in the finest Unix tradition, is one less character to type.
