ok... more details worked out and just a couple points missing. I added
details for if the user has a working input device but may want to
connect another bt device. This might be nice early in the install for a
bt mouse for example so keyboard shortcuts don't have to be used for the
whole install.

These are the steps an installer will need to fully install a Linux
desktop using a Bluetooth keyboard and mouse only. Every distribution
needs to implement this kind of workflow in their installer. When the
user is asked a question, it should be easy for them to use just the
keyboard or just the mouse (if only one is present) to answer.

1. Enumerate input devices (scan /sys/class/input), go to 3 if none.
2. Ask user if they need to pair any bluetooth input devices. If no, end.
3. Start hcid and hidd
4. run hid2hci to put any hid mode dongle in hci mode
5. Tell user to make devices discoverable
6. Enumerate input devices again
7. Inquiry (Call org.bluez.Adapter.DiscoverDevices())
8. Connect to mouse (api details)
9. Connect to keyboard (api details)
10. Enumerate devices.
11. No devices present still, including plain usb? Jump to 5.
12. Ask user if any remaining devices need to be paired. If yes, jump to 5
13. (Later) copy pairing info from ramdisk to the root of the new system

I think steps 8 & 9 change as we implement dbus pathways. Before dbus,
it would be done by executing
 hidd --search
but eventually could be dbus signals to hidd to search for each type of
device.
