Open Stack

Hi,
some time ago there was a proposal to move away from flavors.
See: https://blueprints.launchpad.net/nova/+spec/no-flavors

and the mailing list discussion:

Personally I think it's a bad habit that Microsoft created allowing/encouraging the installation of everything on the "C" drive.  Software like MS SQL is huge yes, but storing a DB on the root disk with the OS files is a bad practice.

Not to mention the complexity of managing so many different flavors.
