[archiso] Add archiso_shutdown hook.
STATUS: Working (std boot, loop_mnt, pxe) with copytoram=[y|n]. NEEDS: initscript > 2011.07.3, mkinitcpio > 0.7.2, mkinitcpio-busybox > 1.18.5-1 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) [#1] http://mailman.archlinux.org/pipermail/arch-projects/2011-July/001549.html [#2] http://projects.archlinux.org/initscripts.git/commit/?id=1fa7b4b453e96533ae1db3630031285e5fc302b3 [#3] http://mailman.archlinux.org/pipermail/arch-projects/2011-August/001749.html Signed-off-by: Gerardo Exequiel Pozzi <vmlinuz386@yahoo.com.ar>
