I am trying to figure out how to get FreeNAS 8 to sleep when inactive and, ideally, wake on lan activity (or, less ideally, wake on a WOL magic packet). However, as I've tried to search for information on how to do this, almost all discussions seem to be centered on FreeNAS 7. Also, the tools included in FreeBSD to do this seem to be missing (i.e. acpiconf, etc.).

Is there a way to get FreeNAS 8 to sleep and wake so that I don't have to leave the server running all the time? Given its usage level, it seems a waste to have the server running constantly.
