::: tip
Suggestions on how to set the partition size: Generally speaking, there are at least two mount points in a linux system, namely / (root directory) and swap (swap partition), among which / is required; Suggest several directories and sizes for general mounting: /swap directory 32G # If the memory is less than 4G, it is twice the memory. If the memory is greater than 4G, the size of the memory can be the same. /boot directory 400M # The static link file of boot loader, which stores the programs related to Linux startup / (Root) directory # all remaining
