How to create Debian preseeded ISO from macOS?

Question

I would like to create a preseeded Debian ISO, but I only have a Mac available to do this.

The instructions for creating the ISO is straightforward, but it involves the appending of a file using cpio, which is not supported on the Mac.

Has anyone successfully created a Debian preseeded ISO from a Mac and can share alternative instructions on how to make this work?

Answer 1

There's a web based build service for custom Debian installation ISO images. It does not use the Debian installer, but instead the FAI system.

Have a look at https://fai-project.org/FAIme

Answer 2

Honestly mate when I've had to do this , I've spun up virtualbox and worked on the ISO in there.
