Add the shutdown KEYWORD to those scripts that start persistent services to allow them to do a "clean" shutdown. I purposely avoided making changes to network-related stuff since the system shutting down is pretty conclusive, and there may be complicated dependencies on the network that I would rather not try to unravel. I also skipped kerberos-related stuff for the reasons above, and because I have no way to test it. 2008-07-16 19:50:29 +00:00			`# KEYWORD: nojail shutdown`

Prepare for the removal of set_rcvar() by changing the rcvar= assignments to the literal values it would have returned. The concept of set_rcvar() was nice in theory, but the forks it creates are a drag on the startup process, which is especially noticeable on slower systems, such as embedded ones. During the discussion on freebsd-rc@ a preference was expressed for using ${name}_enable instead of the literal values. However the code portability concept doesn't really apply since there are so many other places where the literal name has to be searched for and replaced. Also, using the literal value is also a tiny bit faster than dereferencing the variables, and every little bit helps. 2012-01-14 02:18:41 +00:00			`rcvar="powerd_enable"`
Use ${name} in pathnames where appropriate. The sendmail script already was on this way, but it didn't reach the end of it yet. 2005-10-28 16:55:38 +00:00			`command="/usr/sbin/${name}"`
When stopping powerd, set the CPU frequency back to its maximum value (i.e., what it was almost certainly at before powerd was started). Submitted by: R.B. Riddick MFC after: 3 days 2006-08-27 11:04:39 +00:00			`stop_postcmd=powerd_poststop`
