+NOTE: The memory sizes are only "recommended". It really depends on the amount

When KDUMP_KERNELVER="kdump" (on ppc64 because there's still a kernel-kdump

package) was set, then the script failed to find the kernel. The problem was

that it checked for a relocatable kernel, but, of course, the kernel-kdump

is not relocatable.

This patch

- implements "try-restart" in the init script

- adds a udev rule that uses "try-restart" to reload the kdump kernel

in case of a memory or CPU hot plug event
