#  General comment of a caveat here: INITRD_installation() must be
#  reentrant and only install the INITRD handlers if they're not
#  already installed. This is necessary due to a kinda chicken-egg
#  problem: the first time initramfs creation is attempted, we did't
#  necessarily run the INITRD package installation hooks yet, hence
#  we may be unable to properly create the initramfs image. "Easy"
#  solution is to just try to install them always, it's cheap and not
#  dependent of package install time magic.

#  Parameter passing case - since this is invoked by the kdump-load
#  script, we must be sure that the INITRD package is available.

        #  then install kdumpst before rebooting. With that, creating an
        #  initrd fails here since it relies on "uname -r". To prevent such
        #  unhandled error, check if this kernel's modules directory exists.
