Initramfs gets little more complicated in case of kdump kernel boot. It is used to automaticaly save the old kernel's image (/proc/vmcore) to a local filesystem or remotely thru NFS/FTP/SCP etc. It also does things like filtering the vmcore or other housekeeping jobs. Here also different distros have different approaches.
