I am working now over 2 years on a package manager, it build the full cross toolchain from scratch and install the system. Everything can be is compiled . It’s almost done.

I would like to know now how can I make a live iso CD from the system my package manager have generated. Because I am starting to make my own distro now.

This is my project link by the way:
https://github.com/fulgurance/ism

I can’t find any good tutorial to do that.

(That system is under a virtual machine)

I tried already to find tutorials and ask the LFS community, but they don’t have any tutorial for that.
