When there's no kdump initramfs for lsinitrd to inspect with, there will be an error:
# kdumpctl start /boot/initramfs-3.16.0-rc7+kdump.img does not exist
Usage: lsinitrd [options] [<initramfs file> [<filename> [<filename> [...] ]]] Usage: lsinitrd [options] -k <kernel version>
-h, --help print a help message and exit. -s, --size sort the contents of the initramfs by size. -m, --mod list modules. -f, --file <filename> print the contents of <filename>. -k, --kver <kernel version> inspect the initramfs of <kernel version>.
No kdump initial ramdisk found. Rebuilding /boot/initramfs-3.16.0-rc7+kdump.img [..]
In addition, lsinitrd is a slow operation. We only run it when it's fadump mode, to speed up in kdump mode.
