我正在尝试将所有文件、配置、所有内容复制到新的 btrfs 分区,而无需重新安装。
到目前为止,我尝试过的方法是进入实时 CD 会话(实际上是从单独分区上的 iso 启动的),然后使用rsync
它将所有内容从主分区复制到新分区。然后更新新分区fstab
以获得新的 UUID。最后update-grub
。
这似乎有效,一切都正确复制,具有正确的权限和所有权,grub 为新分区创建了新的菜单项,尝试启动它似乎也有效!问题是它仍然启动到旧分区。即使我在启动时选择了新的菜单项。
我也尝试了所有这些,但rsync
用替换cp -a
。

这是fstab
新旧分区的文件。
旧 fstab:
# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point> <type> <options> <dump> <pass>
UUID=11a64844-0379-4d5c-8e2a-e06ff3f79619 / ext4 errors=remount-ro 0 1
# /boot/efi was on /dev/sda1 during installation
UUID=C040-6244 /boot/efi vfat umask=0077 0 1
/swapfile swap swap defaults 0 0
UUID=f4f71706-d44b-42a4-8617-50eed11c5650 /boot/recovery ext4 ro 0 0

这里/boot/recovery
就是我之前提到的 iso 分区。
