Purpose: we need this for propertly unmount $cow_device, used for persistent dm-snapshot devices.
This hook is based on work from Tom Gundersen[#1], but adapted for archiso things (specially the shutdown script)

STATUS: The work around this is finished (cow_persistent + archiso_shutdown hook). Tested with loop_mnt and pxe_nbd and combined with copytoram=. I am just waiting for next release of initscripts/mkinitcpio and rebuild of mkinitcpio-busybox, to adjust final changes that can be needed.
