[Openstack-devel] RFC: starting daemons after install

[ghe. rivero]

Hi Loic,
   I like the idea of having a preseed to disable the scenario, making
them boot by default.

But I strongly believe that we need to aim at "apt-get install openstack" => something is working by default. If no daemon starts by default, we can't achieve this. The default configuration should be the simplest possible use case. For nova it means basically what you get after running http://wiki.debian.org/OpenStackHowto manually, that is a monomachine installation that does most of what a newbie would expect from a cloud solution.
