Well, it's supposed to contain the same information. I think the 32 bit boot protocol, i.e. the communication between the "setup" part of bzImage and the real Linux kernel, was "explored" and used by kexec first and then "standardised" by Linux developers. Therefore, the documentation appeared first in kexec-tools and then some kernel developer put it into documentation tree of the kernel. Maybe it would make also sense to remove that part of documentation from kexec and just refer to the (more up to date) Linux documentation. But I leave this up to your decision. I just discovered that mistake. Bernhard _______________________________________________ kexec mailing list kexec@lists.infradead.org http://lists.infradead.org/mailman/listinfo/kexec
