Boot failed with systemd init

[s ren]

Hi,

    I want to boot a linux with systemd init by qemu,  but there is an error when booting as shown below. I had tried generating img with disk, and it works fine. But a img without disk cannot work.

This is my buildroot-config.

Hey,

i have the same problem.

I have done some searching and i was able to narrow it down.

The problem is with your new linux config.

If you overwrite their linux config, it will forget the nodisk option during image creation. The image still is called nodisk, but it is a disk image.

Best fix currently is simpyl to write your own br-base.json.

Greetings
