Do you know the kexec kernel patch?

Only the first booted kernel need this patch and
can load any other kernel into the RAM and switch
to the second without reboot. *G*

Maybe not the best links - just some quick found links:

I haven't played a litte bit on a my laptop once but tommorow I will
got a NSLU2 because it is ARM powered like the Neo and some ideas
could be tested with it before getting the Neo :)
On the NSLU2 I will play  with debian and kexec to install a pre-system
on the flash once and then boot a second system from USB.

So I think kexec will be possible on the Neo1973 you  could have several
systems parallel and when you need a stabil system for normal life you
choose. No idea if this will be interesting for normal user, but for
shure for hackers like you ;)


PS: I love hacks like kexec and linux-vserver :)))
    So good to have low level delelopers here ;)
