Debian Installer for Live systems ================================= Introduction ------------ Debian-installer (d-i) is the preferred way of installing debian based systems. It runs in the initrd/initramfs (see notes/DebianInstaller). Ubiquity is developed by and used in ubuntu as its graphical desktop installer (alternative and server use pure d-i). Ubiquity uses d-i code as its backend, is a complex beast, and unfortunately not very modular (see notes/Ubiquity) di-live's objective is to provide the ability to install a "live" debian based system to the harddisk, leveraging the power/flexability of d-i, with a completely modular implementation (least amount of assumptions) that can be used by upstream (eg. as an ubiquity depends - seperation of concerns). Source structure ---------------- git-branches #vanilla prestine code downloaded from upstream #master patched upstream code and actual di-live code git-diff vanilla compat/ git-diff vanilla d-i/ di-live - drives the installation (similar to d-i's main-menu) di-live.d/ - component directory (executed in alpha-numeric ordering) d-i/ - upstream d-i source code compat/ - compatibility scripts as d-i code assumes running in initrd/initramfs cli syntax ---------- The init script will execute di-live (on new vt) if the boot param "di-live" is present on /proc/cmdline. di-live may be executed manually in a live system aswell. Syntax: di-live [options] Debian Installer Live Drives the installation, executing components according to alpha-numeric ordering, and responsible for dynamically assembling the menu and executing components when they are selected. Similar to d-i's main-menu, di-live's menu will only be visible when debconf priority is low or medium. Priority is reduced when a component fails, and returns to original level when next component completes successfully. Options: -d --debug Set DEBCONF_DEBUG=developer DEBIAN_FRONTEND=readline
