搭建完根目录系统后，通过nfs挂载出现以下错误[    5.906998] VFS: Mounted root (nfs filesystem) on device 0:14.

看一下你的Lib库，我之前是应为usr/lib中的内容出问题导致的

仰望星空之云

试试：
cd /etc/init.d
chmod 777 rcS

不行的话就试试：
ln -sf /dev/null /dev/tty2
ln -sf /dev/null /dev/tty3
ln -sf /dev/null /dev/tty4

楼主解决了吗？我原来在Ubuntu16.04可以，后来在ubuntu18.04也成这样了
