| Basically there were two ideas according to Zaurus boot:
|
| 1. use kernel+initramfs in kernel partition and let it kexec /boot/zImage

which leaves CMDLINE intact from /boot/zImage and thus behaves as a
non-broken angelboot, right?

| 2. use rescue flash partition to keep our boot+reflash system which will
|    be executed by kernel from 1st point

would be rescue filesystem be kernel+init(c)ramfs or a 'real'
filesystem? Would it include e.g. wireless-tools and parted? I'm certain
~ we can do all that in less than 7MB, especially with uclibc+thumb
(non-collie).

| Personally I would go into 1st way if we are able to get working
system in
| ~400-500KB of initramfs (minimal Zaurus kernel for c7x0 was ~700KB).

We would need only busybox and kexec-tools[1] in there, right?

Koen

[1] does busybox have a kexec applet already?
