h2. Requirements

https://trello.com/c/to0NYlGk/7-using-discovery-without-dhcp-2

I would like a boot disk option that provides the following:

* A single ISO that allows me to provision a system against any configured hostgroup on the Satellite.

* The ISO would not require me to pre-create a host in Satellite.

* The ISO would allow me to provide a user provided IP address or use DHCP to find the Satellite server.

* The ISO will be generated on the Satellite

* The ISO will provide a means to provision via a Capsule

* The functionality to generate the ISO will be exposed via the API, UI & CLI.

* Functionality to provide a local IP and VLAN to the target host

h3. Bootdisk

In the bootdisk approach, the Generic bootdisk would be modified to provide a menu like the one shown below:

!bootdisk.png!

*Notes*:

* If the user does not have DHCP, they may configure networking manually.

* The provisioning URL can be customized, for example, if DNS is not available and you need to use an IP

* If the user wants to build an existing host, they can boot from the existing record

* Otherwise they can create an entirely new host

If creating a new host, iPXE chainloads off of the Foreman server.

*Workflow*

They are prompted for a host name:

!new_host.png!

And then hostgroup, and (if enabled) organization, and location:

!hostgroup.png!

!org_select.png!

!loc_select.png!

Finally:

* iPXE Boots off Foreman

* Foreman creates the new Host, and runs orchestration

* Server boots vmlinuz/initrd

* Loads kickstart

* Provisions as normal

*This is ridiculously insecure.*  

Options:

* Have bootdisk ask for login

   * Only supports HTTP (plaintext)

   * Foreman if SSL is enabled does not allow HTTP login

* Tokens

   * Have a wizard that lets a user generate a bootdisk image with embedded tokens, that give access only to specific host groups/orgs/locations
