>Description:
	amd can mess up the mount maps in a way that 1) causes df to hang and 
	I think causes the system to periodically hang too.

	This is something that started happening only in the last few days.

>How-To-Repeat:
	insert this line into /etc/amd/master:

		/n /etc/amd/amd-n

	insert these 2 lines into /etc/amd/amd-n

	/defaults	opts:=rw,intr;fs:=${autodir}/${rhost};type:=host;rhost:=${key}
	*		;

	(re)start amd in the normal way.

	cd /n/name-of-a-machine-that-is-down
	<hang>
	hit ^C's until one returns to the shell.

	df
	<hang>
	hit ^C's until one returns to the shell.

	at this point df will always hang until the machine is rebooted.

>Fix:
	no idea.
