Running Android in chroot

[Magnus]

I'm working on a project where the goal is to run Android in a
chroot'ed environment from Ubuntu.

As of now I have a kernel for Android running (compiled from
http://nv-tegra.nvidia.com/). From that kernel I can start both ubuntu
and Android depending on what init I choose from uBoot and pass to the
kernel.

The thing is that I want to boot into Ubuntu and after that start
Android inside a chroot.
After I run the command:
chroot android/ /init
Android starts and the init program starts executing everything in the
init.rc file and the problem is now that it stops when hitting the
line:
mount rootfs rootfs / ro remount
with the error:
init: Cannot mount the device rootfs at / as rootfs file
system...retrying

So I wonder what might be wrong, can/should I do anything different
when starting Android or are there anything I can do to fix the
mounting issue?

I have a Harmony board if that might change things.

Hi,

You don't have to remount /. comment out the line.

About Android on Ubuntu, see my slides.

Hi,

Thank you for your response, I've commented out the mounting part and
also changed the line in NetLinkEvent.cpp and now Android starts up
and I can enter the console, no graphics yet.

one thing remains and that is that the nvrm_daemon complains that it
cannot find /dev/nvhost-ctrl which is understandable because it does
not exists, any ideas on how to fix this?
Can I create it myself, or should I change anything?
