Let me see if I understand it correctly:

* on (non-hx4700) bootldr machines /boot/zImage will hold kernel +
initramfs that kexecs a different kernel
* on hx4700 the kernel partition holds kernel + initramfs that kexecs a
different kernel (/boot/zImage?)
* on angelboot (read: zaurus) machines the kernel partition holds
stripped down kernel + initramfs that kexecs a second kernel (with more
dirvers) with a bigger initramfs which kexecs a third kernel to boot
into final userspace
* we leave u-boot machines alone for now, since most u-boots are quite
sensible nowadays.

Marcin: is that the same idea you had for angelboot machines, or will we
repartition flash and put in our own rescue filesystem?

All in all this seems to becoming close to the debian-style initramfs
installer we have wanted for angstrom for a long, long time.

Koen
