- What I meant was that shutdown on an NFS server should send messages
- only to clients that have filesystems mounted from that server, as listed
- in the server's /etc/rmtab. I didn't meant to imply that I thought shutdown
- should cause an unmount on the client. Of course it shouldn't!

- Hmm...we have Suns on three subnets, and as far as I recall, when
- any Sun that's an NFS server is shut down, most of the Suns on all the subnets
- get the messages. I'll have to test this next time I shut down a system.
- (Most exported filesystems are exported to most Suns. That's why I thought
- shutdown might be looking at the export list.)

- Hear, here! I'd also like a switch where you can specify which hosts
- and/or netgroups to send the messages to.
