FYI..
We've known for quite some time that maintaining a list of packages for
image builds [2] is not ideal. We need to push this review along [1].
This relies on DIB for the package list vs.. us specifying the list in the
variables.
We're going to make this a priority now.
Please review [1]
Thanks!
