no shutdown message(s)

[Gary Hodges]

Kubuntu 5.10

When I issue a shutdown command, e.g.

sudo shutdown -r 9:00

I don't get messages like this:
---
Broadcast message from root (pts/0) (Mon Jan 23 08:53:53 2006):
The system is going DOWN to maintenance mode in 7 minutes!
---

My Debian Sarge machines produce these messages.
