The refactor of StepRegisterAmi to add the from_scratch parameter
incorrectly replaced iteration over image.BlockDeviceMappings with
iteration over the new mapping array when not using from_scratch. This
fixes the regression and renames the parameters to newMappings and
mappings for better clarity.
This provides an alternate mode for the amazon-chroot builder which uses
a blank volume to build the image. It adds StepPreMountCommands to
permit partitioning and format commands to be executed before mounting
the new volume.
This commit moves the Amazon builders of Packer away from the Hashicorp
fork of the goamz library to the official AWS SDK for Go, in order that
third party plugins may depend on the more complete official library
more easily.
