Description of problem:

Comments from David Cantrell:
https://bugzilla.redhat.com/show_bug.cgi?id=693944#c23

What about moving the calculation of the crashkernel value out to a standalone
script or tool (e.g., /usr/sbin/rhcrashkernel) that we can run and get a
preferred crashkernel value for the boot loader configuration file?  During
initial installation, we [anaconda] can use that program to set up the boot
loader and you guys can run it from %post to modify existing boot loader
configuration files.  The %post script could key on the existence of a boot
loader configuration file appropriate to the platform as to whether or not it
should modify the crashkernel value.  You could provide the tool in the
kexec-tools package.

#!/bin/sh
if grep -q Fedora /etc/redhat-release; then
    echo -n
else
    echo crashkernel=auto
