Description Garrett A. Wollman 1994-11-23 15:20:00 UTC 
	Union loopback mounts confuse the unmount-on-reboot code,
	causing it to either lock up, or erroneously report
	filesystem busy errors.

How-To-Repeat: 
	mount -t null -o union /home/src2 /usr/src
	mount -t null -o union /usr/local/src3 /usr/src
	reboot

tim@cs.city.ac.uk (Tim Wilkinson) submitted patches which were 
incorproated by David G. on 23 Nov 1994.  Did these fix your problem?

I have no idea if this is even a problem at present.  It doesn't matter 
for me, since I re-arranged my disks a year ago...
