Root on USB stick

[Russell Haley]

Sorry top post only on my phone and I'm trying to remember from a year ago without my notes...

Isn't rootfs something that we can pass through u-boot variables?‎ I'm sure I've done it but I can't remember how...

I also seem to remember that if ubldr can't find the rootfs it prompts for you to enter something manually‎, which might be good enough for development purposes? Or am I imagining that? I remember the prompt, but not what process launched it.

there is an entry in the kernel configuration file where to find root
by default.

But you would need a custom kernel for this.
