You are also in the unfortunate position that nobody tends to be awake
when you want answers over IRC. There doesn't appear to be anyone in a
suitable timezone - if you can, please stay on IRC so that we can at
least post answers that you can read on scrollback later. I missed you
by only a few hours today.

You really do need to know about Debian (rather than RH) before doing
much with Emdebian - we aren't (yet) at the stage.

I'll add a check to emchain so that if the toolchains are already
installed, it tells you not to bother trying to build them.

The reason there are no docs is, umm, we haven't done an initramfs yet.

So far, Emdebian has only booted on a balloon3 board - it is as far as
we have got. It's all yet to be done.

Unfortunately, you are on your own at that stage and the solution
depends entirely on your hardware. I am looking at weaving emsandbox
into the Debian installer but as I've only managed to get a bootable
root filesystem in the last few weeks, there hasn't been time.

On my test hardware, I would:
1. Boot the device into a development environment (you may have
something similar as an option from the bootloader). You need some way
of interacting with the device during the install. In the long term,
this would be the role of D-I but it needs a lot of work.

2. in your serial console, install the kernel as you would normally.

3. Decompress the emsandbox tarball directly onto the filesystem of the
device - e.g. via a USB key - into the directory that will become the /
of the device. cd to that directory. Run ./emsecondstage.

4. Install the kernel modules over that.

5. reboot.


That page is specific to this one device but it does show how it can be
done. Whether any of that is useful to your own device, I just don't
know at this stage but it might give you some clues.

Hopefully this summer, the various conferences and work sessions will
allow Emdebian to get to the stage where we can actually "launch"
something called Emdebian Lenny (!) with something approaching an
installer, even if it only supports a very small range of devices at
that stage.
