By "cannot performa real deployment test", do you mean that they are all import related and shouldn't really have any change to the deployments? (In which case, no additional testing should be needed), or that these need further testing that haven't been done yet?
Maybe it was a little confusing. As far as I've tested, the import works fine (although it might broke other distros). What I cannot assure is that with the import results is really possible to deploy a system. Let say, it might be a problem with the hostname or suite in sample.seed, for example. I will try that on weekend when I can arrange a second laptop.
Hopefully, this second explanation is easier to understand, although right now I'm not in my best shape...
