Target filesystem has inodes of 256 bytes while debian etch version can read inodes of 128 bytes. -- -- Open Kairos http://www.sergiobelkin.com Watch More TV http://sebelk.blogspot.com Sergio Belkin - ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos -- -- Open Kairos http://www.sergiobelkin.com Watch More TV http://sebelk.blogspot.com Sergio Belkin - ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
