Kaisen-Build

Good evening, I saw that kaisen has the option of creating a live iso with kaisen-build but from the documentation I couldn’t understand it very well, after running ./kaisen-build does it create an iso of my current system? and that?

I would just like to create a live iso with my shell scripts and files that I need to already have inside the live, I use it in my work and I need some files that are already inside the live

I found out the reason for not being able to perform the build by analyzing the debootstrap.log file. In the last line, the following message appears.

chroot: failed to run command ‘/bin/true’: No such file or directory

How can I resolve this? I need to create a live with just 4 files, I will not modify anything in the system I just want it to contain these 4 files.
