[Bug-tar] Problem with --listed-incremental and --one-file-system

[Chris Schanzle]

While doing a test disaster recovery with a Fedora Linux box that has 
/boot and / as separate filesystems, I discovered that during the 
restore of the first incremental, the contents of /boot were removed.  
Below is a similar test to illustrate my problem.  Did I find a bug or 
just a new mistake in my methods?

cd /tmp
rm -rf test*.tar state? test/ restore/
mkdir -p test/loop
mount -t tmpfs -o size=64k none /tmp/test/loop
touch test/file1 test/loop/loop1

find test -ls

tar cvlSfgC /tmp/test-full.tar /tmp/state1 /tmp/test loop .

cp -a /tmp/state1 /tmp/state2
tar cvlSfgC /tmp/test-inc.tar /tmp/state2 /tmp/test loop .

mkdir /tmp/restore
cd /tmp/restore

^^^^^^^^^^^^^^^^^^^^^^^^^^^^    BAD!
