The crash dumper only needs to write to disk or network. The other steps are just things the kexec process does to achieve that aim.

  No, this is not true. If you just boot like a regular operating system, you will trash the crashed kernel making the dump useless.

    A crash dumper does not have to be implemented with a reboot; this is just something Linux chooses to do. I have actually worked on kernel code that performs crash dumps to disk and over the network, if you find that kind of expertise relevant.

      I really do. I believe kexec/kdump does execute in place and does not go through a full reboot, am I wrong ?
