第一次启动总是失败。有可能让它发挥作用吗？
处理修改后的操作系统映像。它使用版本 3.10（Centos 7.6）的内核，但 grub 仍然是旧版本 0.97。
当部署操作系统映像时。它始终停留在[达到目标本地加密卷。]，但重新启动/重置后图像工作正常。根据日志，我发现首次启动期间存在安装问题。
如果我更改挂载点 /mnt 或任何其他路径。它会在第一次启动时启动。因此很明显，initramfs 映像安装在“/”处，当它读取 fstab 时，它尝试在“/”处重新安装根文件系统，但失败了。
fstab 文件：
tmpfs /dev/shm tmpfs defaults 0 0
devpts /dev/pts devpts gid=5,mode=620 0 0
sysfs /sys sysfs defaults 0 0
proc /proc proc defaults 0 0
tmpfs /tmp tmpfs size=64M 0 0
LABEL=/ / ext3 defaults 0 1
LABEL=/var/log /var/log ext3 defaults 0 2
grub.conf：
default=0
timeout=5
