How are official LiveDVDs created? How to build one?

[JamesRuss]

Hi, I was wondering if the scripts or official build procedure were detailed somewhere, I am more interested in those using Debian as a base (LMDE), but any would do of course.

I would like to build my own, but all I could find was about customizing one that's already made, like an official image, I couldn't find much on how those are actually produced.

PS. I hope this was the right place to ask, the other forum categories seemed unrelated, but do move the thread elsewhere if another one is more suitable.

Mint devs use Debian's live-build package https://blog.linuxmint.com/?p=4611#comment-386462

But there is no detailed explanation.

Mint's Ubuntu live installer is here https://github.com/linuxmint/ubiquity
Mint's Debian live installer is here https://github.com/linuxmint/live-installer

These are not really "normal user friendly" things. You might want to look into more "casual" tools like Cubic: https://itsfoss.com/create-custom-linux-mint-iso/

This is non trivial, you start off with chroot and debootstrap and go from there. It is a steep learning curve. If you want to see a script building a custom iso then
https://foxclone.org/index-old.html
Download foxiso51-master.tar.gz, extract it and study foxbuild.sh. I learnt enough to do what I wanted - provide a vehicle for running foxclone, I'm by no means an expert.

That's an understatement for sure. Go for it if you really want to learn, but a lack of handy dandy simple guides generally means that most users capable of it don't have to ask.

That's an understatement for sure. G

I consider myself to be reasonably competent and it took me a LONG time starting from scratch. There is not much material out there to help, and even where there is not easy to understand. I would never have got the ISO booting UEFI without the assistance of another forum member, now sadly deceased.
