The reason is that makedumpfile gets a running kernel's page_size as
a 1st-kernel's page_size. If they are different, makedumpfile cannot
analyze /proc/vmcore and it fails. So I think a configuration file
should be created while 1st-kernel is running.

It is a good idea to ship the configuration files with the kernel RPMs. 
I think you can do it with current implementation, because you need
only one configuration file for one kernel image.

I think you can ship configuration files as follows:

1. Build a kernel file and a debuginfo file.
2. Boot the system with the above kernel file.
3. Generate a configration file from a debuginfo file.
4. Ship the configration file with the kernel RPM.

Any problem to follow the method above ?
