Hi,I just wanted to let you know that I am having progress at building an open nebula (raw image) image with your scripts.Architecture of your scripts are really fine to use common stuff while getting possibility to extend it easily. It really works fine.For the moment I still use a dedicated provider directory with a copy of ec2 provider with some customization. Once everything is ok, I plan to see which tasks could be a "common" set of tasks to place them in common and keep specific stuff in my provider. I will not touch however the ec2 part to avoid breakage.Olivier2013/7/9 Anders Ingemann <anders@ingemann.de>

I actually forgot to mention that. Right now *all* tasks are in the
ec2 provider dir, I did this because making tasks generic from the
get-go would make no sense.
With only one provider there wasn't a pattern to generalize from.
If you think anything can be reused, feel free to rip the guts out of
the ec2 provider and stick it in the common/ folder.
There should probably be a task/ folder in there instead of a simple
module. Same goes for assets I guess.
