Fedora 跨版本升级切记得先取消NTFS挂载

今天使用光盘升级Fedora12 到 Fedora13, 结果在升级过程中出现异常， 主要信息如下：
------------------------------------------------------------------------------------------------------------------------
anaconda 13.42 exception report

通过异常信息可知，是外挂的NTFS分区导致了升级异常。
升级前注释掉 /etc/fstab 中NTFS的相关字段， 升级完成后恢复即可。
