Ubuntu for DevStructure

Build a custom Ubuntu ISO for Vagrant by downloading, extracting, tweaking, and packaging the stock Ubuntu ISO.

Build dependencies

• curl(1).
• hdiutil(1), and therefore Mac OS X. It may be possible to relax this dependency but it has not been investigated.
• m4(1).
• mkisofs(1) from the cdrtools package available from MacPorts or Homebrew.

Runtime dependencies

The results are bootable ISO images and so should run on any i386 or amd64 hardware. They are only tested in VirtualBox.

Features in the ISO

• Network access is configured using sane default settings. WiFi is not supported.
• The hostname is vagrant; the domain is vagrantup.com. These are configurable.
• The system clock is set to UTC.
• The entire disk is partitioned ext4 without LVM.
• The default kernel for the architecture is used. linux-server for amd64 and linux-generic-pae for i386.
• The root and vagrant users exist; both their password are vagrant. Vagrant's standard insecure SSH key is authorized for vagrant. These are all configurable.
• OpenSSH server is installed.
• VirtualBox Guest Additions are installed.

Building

Building ISO images:

./build-iso

Building virtual machines through VirtualBox:

./build-vbox

Building Vagrant boxes:

./build-vagrant

There are matching clean-{iso,vbox,vagrant} programs that remove the products of their build counterparts.

The Makefile contains targets for common build tasks.
