note that at_shutdown has a new parameter to indicate When
during a shutdown the callout should be made. also
add a RB_POWEROFF flag to reboot "howto" parameter..
tells the reboot code in our at_shutdown module to turn off the UPS
and kill the power. bound to be useful eventually on laptops
pages.
For those of you that don't know, here is an example of how the .Fx
macro is used:
The xyzzy command first appeared in
.Fx 2.2 .
Will expand to:
The xyzzy command first appeared in FreeBSD 2.2.
so that people can look and comment.
I'll add the at_fork and at_exit immediatly, but I'll
add teh at_shutdown later as it's more extensive
and I desire people's comments..
