[Simpad-general] root/boot environment

Hi all,

Due to the setup of the international mailing list I switch to English
(sort of :).

Okay, I see. Since I have no iPAQ and due to my ISP-setup I don't want
to be online all the time. I will stick to a nfs-based build
environment. I think I will use a nfs-root setup. That way I have
complete control without the need to re-flash the SIMpad unless I change
the kernel. Actually I can hopefully even simulate the cramfs-read-only
setup(and switch between different environments) and test all that stuff
without flashing.

Now the above is nice for testing and development but also leads to a
natural wish to the boot-manager writer. At least if I want to actually
use the SIMpad for some other than development. :) Would it be possible
to implement some sort of primitive boot-selection, e.g. different
kernel-command lines(different root= or init= kernel-parameters). Maybe
I could emulate a mechanism sufficient for my purpose with some change
in the kernel(first try net, if that fails use some local root) but I
don't think that is the place such a thing belongs to.

Regards, Peter
