[Bug-tar] Listed-incremental and old symlinks

[Peter Kronheimer]

Sorry to keep on at this. I am now using tar 1.15.91. The attached 
script uses --listed-incremental in an attempt to recreate an exact copy 
of an existing directory. This time, a symlink is replaced by a 
directory. The setup is:

The source directory is initially:

        testbackup/
        testbackup/aa/
        testbackup/aa/1/
        testbackup/aa/2 -> 1 (symlink)

I execute tar with --listed-incremental. Then the source directory is 
modified: the symlink is deleted, replaced with a directory, and a file 
is created:


        testbackup/
        testbackup/aa/
        testbackup/aa/1/
        testbackup/aa/1/test-file
        testbackup/aa/2/

I execute tar again with --listed-incremental. The two tar files are 
then extracted in a new directory ./testrestore using 
--listed-incremental, in the hope of recreating the second directory 
structure above. However, we end up with:

        testrestore/
        testrestore/aa/
        testrestore/aa/1
        testrestore/aa/1/test-file
        testrestore/aa/2 -> 1 (symlink)

See the attached script for details.

Thanks again,
Peter
