Re: [Bug-tar] Cannot change mode for symbolic links with tar 1.26

[Paul Eggert]

Thanks for the bug report.  I can't reproduce the problem on my Fedora
14 x86-64 host (see below), so I expect it has something to do with
how tar interacts with your platform.  Can you please send the output
of the shell command:

  LC_ALL=C strace -o tr tar -xf directory.tar

(or equivalent, using "truss" or "ktrace" or whatever)
on your host?  For convenience I am attaching the gzipped
'tr' file that I got on my Fedora host, which you can compare
to yours.

Here's what happened when I tried to reproduce the bug,
and everything looks like it worked OK:

$ mkdir directory
$ for i in a b c d ; do touch directory/$i ; done
$ ln -s a directory/1
$ ln -s b directory/2
$ ln -s c directory/3
$ tar -c directory > directory.tar
$ mv directory directory.old
$ tar -xf directory.tar
$ find directory.old directory -ls
