While playing around with Win2K3 recently, I noticed that it brings up a
dialog at every reboot / shutdown and asks for a reason for said reboot
/ shutdown. So I was bored tonight, and decided to implement that
feature in FreeBSD's reboot(8) with a -r flag. Here's a diff against a
-CURRENT reboot.c, checked out about five minutes ago.
