h1. Bootdisk
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
h2. Approaches
h3. Bootdisk
In the bootdisk approach, the Generic bootdisk would be modified to provide a menu like the one shown below:

*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
