Different images

Besides Live CD/DVD images, other images are unsupported. These images are different and doesn't work with Customizer.

Minimal CD

The minimal CD contains only packages needed for downloading most recent packages for installation. Unlike Live CD/DVD, it does not have squashfs compressed image for remastering purpose.

Alternate install CD

The alternative image contains only installable Debian packages. Similarly, it does not have the necessary squashfs compressed image for remastering purpose.

Debian releases

Both Debian and Ubuntu ISO images uses squashed filesystem, but Debian ISO image structure is different from Ubuntu. Customizer is not designed to handle image structure other than Ubuntu-based.
