Hi Robert,

I had some trouble getting the image created with this guide, and wanted to add some context so other people don’t burn hours and hours trying to debug this like I did.

I ran into the below error while trying to boot the image (this is the output via the serial debug header):

[    2.909599] Kernel panic - not syncing: No working init found.  Try passing init= option to kernel. See Linux Documentation/admin-guide/init.rst for guidance.

Turns out that the “Copy Kernel Modules” step breaks the symlink for the /lib folder when copying the kernel modules, causing the boot to fail. I fixed this by copying the contents manually instead of using your tar command directly.

Thank you for your guides and tools, they are worth gold when working with the BBB!

Good catch @Mias yeah after the usr-merge migration of Debian, we need to move all these to /usr/lib/modules/
