Subject: [PATCH] dracut-ramdisk: fix support for elements with
 ramdisk-install.d

Copy all of TMP_MOUNT_PATH into the ramdisk so that
ramdisk-install.d actions are respected.

Includes a workaround for a bug in Dracut that caused the copy
to fail.

Also moves init instead of copying it so we don't conflict with
the Dracut init.

Change-Id: Ia8d7b210369fe7eb7ab239cbdb7f96841104a35d
Closes-Bug: 1403121
