我需要压缩磁盘上的根分区空间，以便为安装另一个发行版创建一个新分区（我现在有 Ubuntu/Kde Plasma，我想与 EndeavourOS 进行双启动）。我想我知道如何做到这一点，但由于这是一个相当危险的过程，我可能需要征求您的建议！
配置显然很简单（GParted 和 KDE 分区管理器都给了我这个：）
未分配
2MB
/dev/nvme0n1p1
挂载点：/boot/EFI (fat32) 300MB (已使用 5.24MB)
/dev/nvme0n1p2
挂载点：/（ext4）238.17GB（已使用 127.08GB）
未分配
7.20MB
但是当“lsblk”给我相当多的循环时，这就是为什么我更喜欢在丢失数据之前询问：

我想创建一个新的分区（~70GB），占用“/dev/nvme0n1p2”（可用空间 110.08GB）的空间，我是否可以指示新扇区，考虑到它们与空间成比例？我的意思是，如果这是分区：
/dev/nvme0n1p2（开始）618496（结束）500103449（总扇区数）499484954 238,2G
我可以设置类似
/dev/nvme0n1p2（开始）618496（结束）353300970（总扇区数）352682475 168,17G
/dev/nvme0n2p1（开始）353300971（结束）500103449（总扇区数）146802479 70,0G
我可以用 fdisk 来做吗？我知道我可以在安装新发行版时直接执行此操作，但我觉得这有点冒险，我想单独执行此操作。有什么建议吗？
谢谢R
