Got me revisiting star :). Isn't Jörg Schilling amazing? Wow. Looks
like if you use the -O option when creating your archive with star it
will

       -O     Be  compatible  to old versions of tar.  If star is
          invoked with this option, star  generates  archives which
          are  fully  compatible  with  old UNIX  tar archives

Eg:

{383} star -cO gnue/ > ~/tmp/gnue_cvs_backup.star
star: 1272 blocks + 0 bytes (total of 13025280 bytes = 12720.00k).
{384} tar tf ~/tmp/gnue_cvs_backup.star | head
gnue/
gnue/CVS/
gnue/CVS/Root
gnue/CVS/Repository
gnue/CVS/Entries
gnue/www/
gnue/www/CVS/
gnue/www/CVS/Root
gnue/www/CVS/Repository
gnue/www/CVS/Entries
Exit 141
{385}

No errors reading archive! yay!

I've tested usingn this option with good results. Without it causes tar
to spit out to stderr: 'tar: Skipping to next header' for each file.
