[OpenAFS-port-darwin] Conflicts when network disconnected

[Thomas Jordan]

I wrote a simple script that I execute from the terminal to unhang my 
laptop when this happens.

stopafs:

	OwenMeany:~ jordant$ more /usr/bin/stopafs
	#! /bin/bash
	sudo umount -f /afs
	sudo /sbin/kextunload -b org.openafs.filesystems.afs
	OwenMeany:~ jordant$

I also linked /usr/bin/afs to the OpenAFS file in 
/Library/StartupItems/OpenAFS/. The file in this path is the one that 
the installer puts there and directs you to use to start the client.

These two changes allow me to start and stop AFS at will. voila'

One warning though. If there are any afs resources open (e.g., files) 
stopping afs _will_ kernel panic your machine. In earlier versions of 
afs simply having a terminal with its pwd in afs space will panic the 
machine if afs is stopped.

Enjoy,
