>Environment:

	FreeBSD 4.0-STABLE #1: Tue Jul  4 05:48:30 CEST 2000

>Description:

	'df -t nonfs' lists, if two partitions are mounted
	to the same mountpoint with 'union', one of them
	twice and omits the other. 'df' by itself lists both,
	as expected.
	This also affects the "daily" report to root,
	/etc/periodic/daily/400.status-disks

>How-To-Repeat:

	$ mount -p | grep ftproot
	/dev/ad1s1e     /ftproot        ufs rw,noatime  2 2
	/dev/ad2s1e     /ftproot/pub/stuff     ufs rw,noatime  2 2
	/dev/ad3s1e     /ftproot/pub/stuff     ufs rw,union,noatime    2 2
	$ df | grep ftproot
	/dev/ad1s1e     17255046 10381956  5492688    65%    /ftproot
	/dev/ad2s1e     48443416 43861994   705950    98%    /ftproot/pub/stuff
	/dev/ad3s1e     38779472  7757158 27919958    22%    /ftproot/pub/stuff
	$ df -t nonfs | grep ftproot
	/dev/ad1s1e   17255046 10381956  5492688    65%    /ftproot
	/dev/ad3s1e   38779472  7757158 27919958    22%    /ftproot/pub/stuff
	/dev/ad3s1e   38779472  7757158 27919958    22%    /ftproot/pub/stuff
