[Server-devel] Booting from a big USB stick

Hi, Gerhard

The trick is to separate the server software from the content. Install 
the basic IIAB on a smaller SD card (e.g. 16GB). Then mount the 128GB 
usb drive (mount /dev/sdb1 /media/usb0 for example). IIAB expects the 
content to be in /library. This should be possible by a symbolic link 
such as /media/usb0/XC /library. XC is a folder containing the content 
whereas usb0 is a partition. The original installed content in /library 
on the sd card needs to be copied to the XC folder on the USB stick 
before the symbolic link is made. In principle, Ansible should recognize 
the /library (XC folder) and operate as expected.

Tim Moody has an img of the basic installation which should be perfect 
to set up the SD card (simple dd). I am looking forward to trying that. 
I am hoping that the img sets the 'box' (hotspot). This should mean 
everything can be done headless via ssh.

As always, it will be an adventure.

Tony
