# 探索linux系统的引导及启动过程

## 写在前面

近来由于安装openEuler 22的系统,但是从kernel 5.1开始sd设备在sys总线上的注册也[变成异步](https://github.com/torvalds/linux/blob/f883675bf6522b52cd75dc3de791680375961769/drivers/scsi/sd.c#L610)的了,

导致在服务器在上多块磁盘时且是静默的情况下会出现os安装在不期望的磁盘上,但是你可以尝试修改将[异步改为同步](https://gitee.com/openeuler/community/issues/I66HWX),但是今天我们提供另外一个解决方案。

最后根据mingetty程序调用login让用户登录->用户登录(完成系统启动)
