Two more questions to better understand it. 

Does QtMoko also work without gta04-init?
And can it be installed in a different partition?

I think other systems have some magic for this. My eeePC with Debian/LXDE
magically finds and dynamically mounts an SD card to /media when I insert it
into the SD reader. Either the built-in or an external one using USB.
And it finds it also if I have inserted it before booting, i.e. I handles removeable
media, but I don't have to...

It even mounts multiple partitions to different /media/NAME nodes.

I don't know how it works (udev rule? a special automounter daemon?) and
it may be also part of the special eeePC debian installation package and not
a standard Debian tool.

But I think such a mechanism could also be integrated into QtMoko and other Distros
so that they can handle any order or type of partitions. And, it could be possible
to access/modify/debug the SHR partition while running QtMoko or vice versa.

Or maybe have two different QtMoko systems in different partitions?

Anyways it could be nice to share some data/media partitions between these

But it can be done with a second SD card with bootloader-upgrade. It also can
be smaller and really cheap. I think 1GB is sufficient. Maybe the old 512MB
that was provided with early Freerunners as well but I have not checked.

Well, this needs two cards and it may be a little more difficult to get the new
bootloader onto the upgrade-SD first.

But the Debian/LXDE hw-validation image even has an entry for apt-get
upgrading these files from the goldelico server. It is not widely made known
because we have no certificate yet and it asks each time for permission.

And it needs a ssh over USB connection to remote control this upgrade.

Can QtMoko somehow support multiple media partitions?
