@tnine:
Is it possible to change an existing installation to use the appliance install?
I couldn't find anything on that in the docs. If I were to try, this is what I would do. Again, I've never tried and I definitely don't guarantee it will not destroy your existing installation.
echo embedded > /etc/platform
and then use the firmware update page in the GUI to install the embedded image.
As for a new install of embedded, this is not done using the Live CD. You have to download the embedded image then use dd or physdiskwrite to write the image directly to the boot device. These instructions are what you're looking for:
