权限或系统影响较大，执行前请核对目标。
常用示例
Example
sudo e2label [/dev/sda1] "[label_name]"
说明
e2label changes or displays the filesystem label on an ext2/ext3/ext4 filesystem. Labels provide human-readable names for filesystems and can be used to mount filesystems by label instead of device name, which improves portability when device names change. If no label is specified, the current label is displayed. Labels are particularly useful in /etc/fstab entries, making system configuration more resilient to device renaming after hardware changes.
