Many interesting poins were mentioned here. I do not think we should use hostgroup in the new host wizard at all. There are too many unrelated things attached to it which does not help us in simplifying the workflow but rather leads us in direction of ‘how to turn existing host form into wizard’.
I do like the idea of host template/blueprint as @lzap mentioned but I do not agree template/blueprint should be an existing host for the reasons already mentioned. Moreover, we have that feature already - just click ‘clone’ button on host show page ;-). This also ties to what @tbrisker proposed for hostgroups - separating various parts and distinguishing between configuration in Foreman and what is reported in facts. In this regard, host template/blueprint is a bit misleading name because it would deal only with provisioning and would be one of the hosts aspects (I intentionaly avoid word ‘facet’ here, though existing facet framework looks like a good fit but I leave it to @Shimon_Shtein to confirm). Creating a host from a template/blueprint (just one type for start, regardless of whether it is virtual or bare metal) seems like a good candidate for the first version of hosts wizard to me.

I see a host as a composition of ‘funcionality/feature groups’ that may or may not be present regardless of implementation. This is useful for extensiblity, because on one of the first steps in wizard could be a set of questions like the following:
- Would you like to use Puppet with this host?
- Would you like to use Ansible with this host?
- Would you like to use Openscap with this host?
- Would you like to subscribe this host to consume content?
Based on the answers, steps could be ommited, which would satisfy the requirements for a short wizard. This is in line with previous suggestions. I just wonder how well this plays with @TimoGoebel’s suggestion about admin and user who installs systems.
I see the suggestions for bare metal capabilities as the first worflow that we should go for. Any other thoughts?
