Not (necessarily) the installer but the program that configures kdump.
system-config-kdump on Red Hat, YaST on SUSE.

I don't see any problems. I don't know how much effort is it to free
already reserved crashkernel memory, but I guess it's not really
complicated. Maybe that "1/32" should be specified on the command line like
crashkernel=>>5
(for 1/32*system_memory == system_memory>>5), OTOH I have no real strong
opinion.

Bernhard
