In general I agree.  The cost of a second kernel and initrd can be
prohibitive in the smallest systems, and if you do a crash capture
with using a standalone app that is reinventing the wheel.

That said.  I can happily run kdump with only 16M-20M reserved.
So on many systems the cost is affordable.
