I have fixed cloud-initramfs-tools, so that it works as expected (eg:
resize the HDD at boot time correctly), and I use cloud-init in my
images. It works very well. Using anything else, like the hacked things
in the current official AWS images, is IMO, a loss of time. cloud-init
is definitively the way to go, as it supports all clouds in a unified
way (and if more have to be added, we should work on it).

I see no reason to use d-i if we can use debootstrap directly. d-i is
IMO less flexible, and forces you to use preseed if you want to run
automatically. I also don't like the fact that you have to actually boot
the virtual machine to have the installation happen, when this is really
not needed.

Same problem here. Running any kind of virtualization is absolutely not
needed to build a cloud image.
