Buildroot Login Incorrect for Root
 
Ok I created a basic buildroot base and with three days of linux kernel tinkering I finally got the damn thing to boot up. :-D

However now I ran into a problem with the login.

The prompt shows up just fine but no matter what I enter, it won't let me log in.

In buildroot there is no password for root until you set one so I don't understand what is going on here. I even tried (chroot)ing into the partition and setting the root password and I still can't log in to my buildroot system.

It should be noted that I am using a standard console (That is, Not a serial line) for logging in.

I can bypass the login all together by setting: "tty1::respawn:/bin/sh" in /etc/inittab so I suspect it is either a problem with "getty", "login", or a configuration issue.

Is this a buildroot bug or a configuration problem???

If its a buildroot bug I will just bypass the standard login program and write my own to manage it.
