Custom Installer Mechanism

[Furkan İnciroğlu]

Hello there,

I have my custom Linux distro which was built from Linux From Scratch.
I want to make also custom graphical installer for my distro. Before
move on graphical installer I also made a ISO. I can install my distro
via ISO without any problem. But my purpose is setting up disk
partition, language and keyboard layout before installing the iso
that's why I need a graphical installer.

My question is about procedures. I am planning to use Python for
graphical installer. First, I am trying to understand how does Ubuntu
installer work? Does Ubuntu graphical installer run on initramfs? How
does ubuntu installer work after booting ISO? How can run my python
scripts to set up disk partition before mounting my squashfs
filesystem on the system?

Could you give me some hints about my way?

Best regards,
