系统启动报错：
Error getting authority: Error initializing authority: could not connect: no such file or directory(g-io-error-quark,1)
原因：磁盘挂载错误引起系统启动出错
解决：

journalctl -xb | grep mount      #根据提示输入命令查看启动错误日志，定位到是home目录挂载出错
lsblk     #查看磁盘挂载情况，发现home目录已经取消挂在了（因为之前做根目录扩容的时候把home卸载了）
vim /etc/fstab      #查看挂载文件，发现里面还有关于home的挂载配置，因此注释掉home目录的挂载配置即可
