Make linux install into bootable iso
 

Ok, I have installed arch Linux on my pc. I want to make my install into a bootable iso with installer to install to my friend's pc. How do I go about this? I am currently using arch installer scripts to install my distro.

Here are two articles from the Arch Wiki on how to do it:
