No doubt you meant that foo should be a symbolic link to tar?
(Your example doesn't say.)

But in that case, I don't see why you'd expect the behavior
described above.  If symlinks are being followed, 'tar' should
behave the same with 'ln foo bar' as it does with 'ln -s foo bar',
which is like this:

$ touch foo
$ ln foo bar
$ tar czfh foo.tar.gz foo bar
$ tar tzvf foo.tar.gz
-rw-r--r-- eggert/eggert     0 2011-01-05 09:43 foo
hrw-r--r-- eggert/eggert     0 2011-01-05 09:43 bar link to foo

This behavior is the same for both 1.22 and 1.25 (I just checked).
tar 1.22 mishandles it if "ln -s" is used, but 1.25 gets it right.

Sorry, I wasn't very clear. I was under the impression that the -h option dereferences symlinks, so that they become regular files inside the archive. Is this not how it is supposed to work?

I assume we're talking about a bug in Amanda here?
I don't recall test cases being submitted to bug-tar.

Where is the Amanda bug report?
