--VbJkn9YxBvnuCH5J Content-Type: text/plain; charset=utf-8 Content-Disposition: inline Content-Transfer-Encoding: quoted-printable I don't know if tar(1) is the culprit or an innocent bystander but this is what I am seeing on 10.1-RC1 (r272468 amd64). The archive appears to be written properly prior to generation of the error message. Although the user is permitted to traverse the parent directory, tar(1) emits the complaint if the parent directory is not readable. Filesystem is UFS. $ tar -czf dtt.tgz -C /data/tftp/thlan . tar: .: Unable to continue traversing directory tree: Permission denied tar: Error exit delayed from previous errors. $=20 $ ls -ld /data /data/tftp /data/tftp/thlan drwxr-xr-x 33 root wheel 1024 2 Sep 20:13 /data drwxr-x--x 4 root wheel 512 23 Apr 09:00 /data/tftp drwxr-x--x 3 john wheel 512 23 Apr 10:28 /data/tftp/thlan # chmod o+r /data/tftp $ tar -czf dtt.tgz -C /data/tftp/thlan . $=20 I haven't played with 10.0 but this behaviour is different to other earlier releases (e.g. 9.3-RELEASE doesn't do this). I have filed a PR [Bug 194477]. --=20 John Marshall --VbJkn9YxBvnuCH5J Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iEYEARECAAYFAlRE0BgACgkQw/tAaKKahKIXaACgwNjIHNscrTQ1ykuwFOtVDl8t zN0An3F6fMO2C1H5esOGkf2KzsGTDbCv =iWtY -----END PGP SIGNATURE----- --VbJkn9YxBvnuCH5J--
