mkinitcpio

mkinitcpio is a script to create an initial ramdisk environment.

Troubleshooting

'/lib/modules/xxxxxxx' is not a valid kernel module directory

When you encounter an error like the header of this section when running mkinitcpio try first to reinstall the linux, linux-headers and filesystem packages. If that does not fix it continue. Look into the /lib/modules directory. There should be a directory called 4.9.8-1-ARCH or similar. Now run mkinitcpio -k 4.9.8-1-ARCH -g /boot/image.img and move the image to the correct location /boot/initramfs-linux.img in the boot directory (back up the old one). After that reboot and it should again work fine (Source: Unix Stackexchange).
