我用buildroot产生的rootfs,每次启动都要登录，有什么办法可以去掉这个登录吗？

找到一个类似的问题： how-to-login-automatically-without-typing-root-in-buildroot-x86-64-qemu
但是他仍然没有解决:
I've asked on the mailing list and Thomas Petazzoni replied that the:
/etc/inittab
should contain:console::respawn:/bin/sh
instead of:console::respawn:/sbin/getty -n -L console 0 vt100 # GENERIC_SERIAL
With qemu_x86_defconfig, the inittab is being used by Busybox' init system, due to BR2_INIT_BUSYBOX=y.An easy way to get it working it to just edit package/busybox/inittab directly, and rebuild busybox:
make busybox-reconfigure
The cleaner way is to use BR2_ROOTFS_OVERLAY.This method does have a downside however: just after login, the message shows:
/bin/sh can't access tty; job control turned off
and as advertised, things like Ctrl+C will have no effect.The /sbin/getty on Ubuntu 14.04 has a -a argument for automatic login, but BusyBox' implementation doesn't.

原来已经有大神踩过这个坑了：
https://www.kancloud.cn/lichee/lpi0/421922
开机自启动
buildroot 根文件系统
修改/etc/inittab:
ttyS0::respawn:/root/logintest -L ttyS0 115200 vt100
新建logintest：
#!/bin/sh
/bin/login -f root
自启动任务在/etc/init.d/rcS中加入即可
export 相关环境变量在/etc/profile中加入。
