        I'm facing the same problem reported back in March, 17 by Wouter
        Verhelst, regarding storing hard links in tar using --transform.
        I'm using tar 1.22.


    I must have overlooked the original report. Please, try the attached
    patch. Let me know if it works for you.


It works!


$ /usr/local/bin/tar cPvf test.tar --transform="s,^basedir,,h" 
--show-stored-names basedir
/
/test
/test_link
$ /usr/local/bin/tar tPvf test.tar
drwxr-xr-x jmpg/jmpg 0 2009-06-25 16:49 /
-rw-r--r-- jmpg/jmpg 6 2009-06-25 13:13 /test
hrw-r--r-- jmpg/jmpg 0 2009-06-25 13:13 /test_link link to /test

But, when I give 'H' in the transformation scope flag it still does the 
transformation:

$ /usr/local/bin/tar cvPf test.tar --transform="s,^basedir,,H" 
--show-stored-names basedir
/
/test
/test_link
$ /usr/local/bin/tar tPvf test.tar
drwxr-xr-x jmpg/jmpg 0 2009-06-25 16:49 /
-rw-r--r-- jmpg/jmpg 6 2009-06-25 13:13 /test
hrw-r--r-- jmpg/jmpg 0 2009-06-25 13:13 /test_link link to /test

Only if I supply 'R' tar does not make the transformation:


$ /usr/local/bin/tar cPvf test.tar --transform="s,^basedir,,R" 
--show-stored-names basedir
basedir/
basedir/test
basedir/test_link
$ /usr/local/bin/tar tPvf test.tar
drwxr-xr-x jmpg/jmpg 0 2009-06-25 16:49 basedir/
-rw-r--r-- jmpg/jmpg 6 2009-06-25 13:13 basedir/test
hrw-r--r-- jmpg/jmpg 0 2009-06-25 13:13 basedir/test_link link to 
basedir/test

so, it seems that some bug(s) still persist.


Best regards,
