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. When
this happens, I will send another [RFC] before inclusion in master (if
no objections of course).

Dirty hacks needs to build this now:
In make_customize_root_image() [configs/releng/build.sh]
pacman -R --root ${work_dir}/root-image --noconfirm initscripts
pacman -U --root ${work_dir}/root-image --noconfirm
initscripts-git-*-${arch}.pkg.tar.xz
sed -i 's@nosuid,noexec,nodev,mode@nosuid,nodev,mode@'
${work_dir}/root-image/lib/initcpio/init # fix for mkinitcpio
sed -i 's@#reexec init@cp /oldroot/sbin/init /sbin@'
${work_dir}/root-image/etc/rc.shutdown # until new rebuild of
mkinitcpio-busybox
