Hello,

I am looking at possibilities of automation of disk image creation (installation) and update.

I ran across tools from Aeolus: imagefactory - http://www.aeolusproject.org/imagefactory.html and Oz - http://www.aeolusproject.org/oz.html

I noticed Oz is used in Heat too. Is there some other tool I could look at?

There are lots of tools for image building. Oz is a bit different from most others in that it actually spawns a VM to do an install, while most other tools simply use a loopback mounted filesystem.

BoxGrinder would probably be your next choice on Fedora. BoxGrinder uses python-imgcreate, but wraps it in a bunch of ruby code where some of the postinstall image tweaking happens. (Personally, I use ami-creator, which is a tiny python script that just subclasses from python-imgcreate and implements a few functions to do the necessary tweaks... no need for ruby here.)

Thanks, Tomas

We use Oz in the context of OpenStack quite a bit.
