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?=E2=80=8E =
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=E2=80=8E, which might be good enough for de=
velopment purposes? Or am I imagining that? I remember the prompt, but not =
what process launched it.=C2=A0

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

But you would need a custom kernel for this.
