In fact, I missed LOTS of spots. My cygwin-specific patches to 1.27 were accidentally not copied to 1.28. I'm fixing it as part of packaging 1.29, which should hit mirrors soon. I'm actually a bit surprised that there were so few reports of this problem in the meantime (I built 1.28 in May 2015, this report was in March 2016, and I didn't find much else about it in the meantime). Maybe that means that text mounts are used much less than they used to be when I took over building tar in 2005, back when setup.exe used to have a now-removed option to create text mounts at install time. --=20 Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org --tAwFFPLB7sV58ueA5ooSrqw2jeakTdXU0-- --qEaCOG2Uj775VAJ7Ig1nufJlgB3jAmx9D Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" Content-length: 604 -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 Comment: Public key at http://people.redhat.com/eblake/eblake.gpg Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQEcBAEBCAAGBQJYSh81AAoJEKeha0olJ0Nq8I4H/1GSim29njk8ann2EApmZlHj gG8oZkWkfMzJu0ACEvNV1OvHOkKzeVWoenGLMllW+RyqEiZuh2qAHAAYwPdfILB6 2f358a8oAaJRHfSy8tdqoZgVKWUBzvi1z606IzVAZa+LB684TcxvuEUe6A9CyqfT C5CwlGo1LWQyAV35AkGtUbzINkhcUucOIlC3oypiPgWV0HG+lBOhehSGnTg9kevG kREmqS52/fkOce4/RPl3kNrj68j5HHekcegk3wT9VBY8TngLYRFyaQsVDUa2C8Oe qAu3EjSkjGYxQHP1IL06RQJFvlD3MCZ8nnWPcAY3rdIqmPFeXuGcTe84axpC9gw= =jF/V -----END PGP SIGNATURE----- --qEaCOG2Uj775VAJ7Ig1nufJlgB3jAmx9D--
