Description pb 1995-05-26 10:40:02 UTC 
	One of the PCs ("client") boots from the other ("server")
	via NFS.

	"client" NFS-mounts its root from "server"
	"server" NFS-mounts a disk from "client"

	If "client" crashes, it is unable to reboot.

Fix: 

Workaround : reboot server.
How-To-Repeat: 
	- boot server
	- boot client

	server$ mount client:/u /u

	(mounting with options -i and -s doesn't help)

	- crash client
	- try to reboot client

		-> message from netboot.com :

	Unable to mount ROOT filesystem: Not owner

Circular mounting is never a good idea.  If you do it, soft mounting 
is mandatory.
