I didn't check that kexec is currently not supported on "arm"
under Debian. :-(
However, I note that there is supposed to be some support for
kexec on arm since 2.6.22 but it is not built-in for the Debian
kernels. Is the reason for this documented somewhere?
The reason for asking is that I was thinking of using kexec
to boot into the armel debian installer without over-writing the
existing "arm" flash on an NSLU2. Is that feasible?
