This patch currently only applies to the "ubuntu-cpc" project.
More and more logic has been going into the hook scripts to decide under which conditions they should run or not. As we are moving to parallelized builds of image sets, this will get even more complicated. Base hooks will have to know which image sets they belong to and modification of the dependency chain between scripts will become more complicated and prone to errors, as the number of image sets grows.
This patch introduces explicit ordering and dependency handling for scripts through the use of `series` files and an explicit syntax for dependency specification.

# Vagrant images are essentially nothing more than OVA's with extra-metadata

# and some preinstalled packages.
|
|
#
|
|
# We can't use the OVA's for Vagrant since Vagrant uses SSH to modify the
|
|
# instance. This build step creates a cloud-config ISO so that Cloud-Init
|
|
# will configure the initial user, creates meta-data that tells Vagrant how
|
|
# to interact with the cloud-init created users, and finally create the OVA.
|
|
#
|
|
# For this step, we make a deriviative of binary/boot/disk.ext4 and install
|
|
# some packages in it, convert it to a vmdk, and then assemble the vagrant
|
|
# box.
