Icon supports multiple image options by building Live CD-style ISO images. It
writes multiple ISO images to a /boot partition, and uses grub to select
between them at boot time (with hotkeys for headless selection). A second grub
instance runs inside the ISO to allow further customization.
Images utilize a tmpfs overlay filesystem, so by default filesystem changes
are discarded on reboot or upgrade. An optional /persistent filesystem allows
data storage across reboots and upgrades/downgrades.
Images optionally self-upgrade by fetching new images from an HTTP(S) source
and updating the configuration of the outer grub instance. This removes the
need for a separate OS instance to perform upgrades (and avoids figuring out
how to upgrade that instance).
