Package: tar
Version: 1.15.91-1
Severity: important

Hello,

since a few days, the backup software "amanda" fails on two of our 
Debian Unstable machines. 

A deeper analyse shows, that the GNU tar have problems with the 
(correct) way, amanda uses it. This results in a try to backup all 
mounted NFS shares of our company. Which will ultimately fail...

To reproduce simply create a directory (/tmp/foo/) with a few files.
Create a directory and mount something via NFS into it. (mount 
computer:/someshare /tmp/foo/bla)

Now try this:
/bin/tar -v --create --file /dev/null \
 --one-file-system \
--numeric-owner --listed-incremental /tmp/someemptyfile
--sparse --ignore-failed-read --totals  /tmp/foo

(this is the syntax, amanda uses when calculating the backup size. 
Unusual, but nothing wrong with ist)

As you can see after a try, the tar DOES NOT ignore the NFS directory.
Without the --listed-incremental is does ignore it correctly.


Cheers, Felix
