How to create ISO image using live-build

How to create ISO Image Using live-build

1. live-build

• ISO 이미지를 제작하기 위해서 사용하고 있는 패키지

2. file tree

config
  │ # stage (bootstrap -> chroot -> installer -> binary -> source)
  ├ bootstrap : base
  ├ chroot : squashfs와 동일하다고 보면 됨
  ├ installer : installer 폴더 구성
  ├ binary : add extra files (installer + bootloader + etc.)
  ├ source
  ├ common
  ├ archives (sources.list 관련)
  │ ├ {name}.list.chroot : live system에 존재 X
  │ ├ {name}.list.binary : live system에 존재 O
  │ └ .deb : local keyring package, live system에 존재 O
  ├ pacakge-lists (iso package list 관련)
  │ ├ .list.chroot_live : only live system
  │ ├ .list.chroot_install : live + installed system
  │ └ .list.binary : only installed system
  ├ hooks (hooking script)
  │ ├ live : live image 
  │ │ ├  .chroot : run after chroot stage
  │ │ └  .binary : run after binary stage
  │ └ normal : regular system image
  │   ├  .chroot : run after chroot stage
  │   └  .binary : run after binary stage
  │ # includes (file copy)
  ├ includes.bootstrap
  ├ includes.chroot_before_packages (before install packages)
  ├ includes.chroot_after_packages (after install packages)
  ├ includes.binary (binary stage)
  └ includes.installer
