If the directory where the kdump.img is saved has no enough space for the kdump.img, after restarting kdump service, it will get an incomplete file named initramfs-xxxkdump.img, the restarting of kdump service failed, but did not remove the incomplete file. So when reboot the system, kdump will load the incomplete file, and then when kernel crash, the kdump will fail because the file initramfs-xxxkdump.img is incomplete.

So, if the dracut failed building the initramfs-xxxkdump.img, kdump should remove the file initramfs-xxxkdump.img so that kdump will not load a wrong initramfs-xxxkdump.img when reboot the system.

Could it be done in dracut?

dracut create a partial image file, it can fail and cleanup the garbage..

Thanks Dave
