    A single function pointer function is suggested because it is the
    simpliest compromise
    I can thing of which should be able to satisfy all.

    The simpliest policy I can think of is
    -flip a bit on _dedicated_ hardware (crash notifier)
    -launch capture kernel (existing kexec)

    Nothing prevents you from implementing multiple policies to be
    executed/selected among from
    whatever is called by the single pointer function.


    My key point is:
    The complexity in my suggestion is a low as it can get, thus reliability of
    kexec (hopefully) is unaffected
    If crash notifiers is implemented by a complex "management system", I
    might loose
    reliability of kexec because of something I basically do not need.

    Or to put it in other words, I you need to implement anything complex
    for managing your policies,
    you should add it yourself and you yourself is the only one being
    affected by increased complexibility.
