[one-users] disable the deletion of an instance

[vincent at vanderkussen.org]

Hi,

On our ONE cloud we deploy images that are part of our "core" 
infrastructure
(dns, DB's, Git, ...)and are not volatile at all. Currently these 
instances
are viewable between all the other instances that come and go.

Is there a way to disable the deletion of such instances so that it's 
not
possible to delete this by "accident".

I was thinking about doing something with ACLs but is there an easier 
way?

Grts,
Vincent
