如何将 grub 配置转换为使用内核设备名称而不是 UUID

我有一堆相同的系统，我想在它们上克隆相同的 openSUSE 12.3 安装。

我已经在 PXE 服务器上设置了 clonezilla。

在另一台计算机上应用磁盘映像后，它无法启动。

这是因为所有分区都被称为它们的 UUID，而不是内核分配的名称（sda1、sda2 等）。

如何将 grub 配置为使用内核名称而不是 UUID，以便映像可以真正移植到其他系统？

我尝试过设置GRUB_DISABLE_LINUX_UUID=true然后/etc/default/grub运行grub2-mkconfig -o /boot/grub2/grub.cfg。我还更改了 中的条目/etc/fstab。

进行这些更改后，系统仍然可以在源计算机上正常启动，但无法在所有其他计算机上启动。 Grub 加载，但仅显示单词“GRUB”，仅此而已。没有其他事情发生。

我目前的情况grub.cfg如下：

# DO NOT EDIT THIS FILE

# It is automatically generated by grub2-mkconfig using templates
# from /etc/grub.d and settings from /etc/default/grub

文件GRUB_DISABLE_LINUX_UUID=true中有特殊选项。/etc/default/grub

添加它，然后运行update-grub，您将获得包含内核设备名称的配置。
