Hi,

This came up recently on my review to add an environment to enable 
Designate in a TripleO deployment.  It needs to set both resource 
registry entries and some user-configurable parameters, which means 
users need to make a copy of it that they can edit.  However, if the 
file moves then the relative paths will break.

The suggestion for Designate was to split the environment into one part 
that contains registry entries and one that contains parameters.  This 
way the file users edit doesn't have any paths in it.  So far so good.

Then as I was writing docs[1] on how to use it I was reminded that we 
have other environments that use this pattern.  In this case, 
specifically the ips-from-pool* (like [2]) files.  I don't know if there 
are others.

So do we need to rework all of those environments too, or is there 
another option?

Thanks.

-Ben
