Comment 3 for bug 194101

I've created a bug task for dpkg, too, because I think it should handle the situation better.
For the record, it fails in the following last block of the last "$mode eq 'auto'" code:
            checked_alternative($sname, $slink, $spath);
            checked_symlink("$spath", "$altdir/$sname.dpkg-tmp");
            checked_mv("$altdir/$sname.dpkg-tmp", "$altdir/$sname");
