A small problem about useless initramfs of kdump should be removed

[Chao Fan]

Hi all,

In my machine, there are 3 useful versions of kernel,
4.17.9-200.fc28.x86_64
4.17.14-202.fc28.x86_64
4.18.5-200.fc28.x86_64
But there are some useless initramfs not removed:
cfan@localhost ~> ls /boot/initramfs* -Alh

The old initramfs of 4.17.6 has been removed after # dnf update, but the
kdump initramfs not.
initramfs-4.17.6-200.fc28.x86_64+debugkdump.img and
initramfs-4.17.6-200.fc28.x86_64kdump.img are useless, every time
updating kernel, I need remove them by hand. So whether it's OK if
kexec-tools can clean them.
My verions of kexec-tools is kexec-tools-2.0.17-3.fc28.x86_64

Thanks,
Chao Fan
