Comment (by sa2ajj):

 Latent build slaves have a special feature: reproducible environment,
 which is a parameter:

 * AMI specification for [http://docs.buildbot.net/latest/manual/cfg-
 buildslaves-ec2.html AWS]
 * `base_image` for [http://docs.buildbot.net/latest/manual/cfg-
 buildslaves-libvirt.html libvirt]
 * `image` for [http://docs.buildbot.net/latest/manual/cfg-buildslaves-
 openstack.html OpenStack]

 The "normal" build slaves would have to create such an environment (e.g.
 [https://github.com/buildbot/metabbotcfg/blob/master/builders.py#L27
 Buildbot's builder configuration]).

 I agree though that either a blog post or an addition to the documentation
 would be helpful for more people to start using this kind of build slaves.
