Since we are mostly working with headless systems, and thus cannot easily observe progress of provisioning., it would be nice to have step between "pending installation" and "finished".
I'm thinking about something like "busy" or similar. Also, not sure if we externally "fail" a system in provisioning?

This way we can tell if it at least went beyond PXE & the initial bootloader. A few use cases in which I really missed it:

• Installing centOS over PXE, sometimes the server wasn't accessible, I've waited an hour only to eventually learn internet connectivity was broken => having an intermediate "busy" step could've informed me that the system is either installing or "fail" if the installation did not go through. If I don't have either of the two states withing a few minutes, it can be implied I have network issues
• Installing windows was very similar, when using the wimaging scripts, I forgot to tell which image inside the WIM file it should use to install, this resulted in a failed build, again, I had to find this one out the hard way (since windows takes some time to install, there is no reason to be alarmed right away)

The caveat is that it should not be mandatory and that, probably, not all provisioning systems have the option to include this intermediate step as part of the templates
