Using fake driver means we need a manual step to set it to something 
non-fake :) and the current introspection process already has 1 manual 
step (enrolling nodes), so I'd like autodiscovery to require 0 of them 
(at least for the majority of users).

Well, if we have a CMDB, we probably don't need to set credentials. Or 
at least we should rely on the CMDB as a primary source. This "setting 
random password" thing is more about people without CMDB (aka using 
ironic as a CMDB ;). I'm not sure it's a compelling enough use case.

Anyway, it could be interesting to talk about some generic 
OpenStack-CMDB interface, which might something proposed below.

Oh, that's interesting. I see some potential overlap with ironic and 
ironic-inspector. Would be cool to chat on it the next summit.

+100, would love to hear.
