After printing all the warnings, shutdown(8) signals init. Ctrl+Alt+Del also signals init (and that's nontrivial to change, because it's in the kernel). Only if the strange -o option is used does shutdown execute reboot(8) or halt(8). I think the canonical low-level interface should be sending signals to init. reboot(8) and halt(8) doing things on their own should be banished to non-default options. (Something should be fixed first so that /etc/rc.d/mixer doesn't destroy the user's settings from single-user mode.) -- Jilles Tjoelker _______________________________________________ svn-src-all@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/svn-src-all To unsubscribe, send any mail to "svn-src-all-unsubscr...@freebsd.org"
