This repository contains recipe to customize the Ubuntu 22.04 Jammy Jellyfish desktop image for an on-site programming contest.

You can go two ways about this:

1. Prepare a custom ISO that can re-distributed.
2. Customize an existing installation.

You can choose to create a customized ISO which can then be simply installed in each machine. To do that, follow these simple steps:

1. Download a Ubuntu 22.04 desktop image. Find download options here.
2. Launch Cubic, configure and find your way to the console in the chroot environment. Learn how to use Cubic.
3. Copy/clone the repository files in the /root directory. Make sure to customize options (user accounts etc.) in vars.sh.
4. Run the install.sh script as root. It should run non-interactive.
5. Proceed with Cubic options, compress and generate the iso.

The ISO can now be re-distributed and installed on machines independently.

If you have Ubuntu 22.04 installed on a machine, you can simply run the scripts on the OS to customize your instance. The following steps should do the trick:

1. Copy/clone the repository files. Make sure to customize options (user accounts etc.) in vars.sh.
2. Run the install.sh script as root. It should run non-interactive.

The scripts install the following utilities:

• Compilers
  • GCC
  • G++
  • Python3
  • Java
• Editors
  • Vim
  • Emacs
  • Nano
  • Sublime text
  • VS Code
  • Gedit
• IDEs
  • Code::Blocks
  • Geany
  • PyCharm
  • Intellij IDEA

Three user accounts are also created:

• admin (for administrative usage, has sudo rights)
• main (for the on-site main contest)
• mock (for the mock contest)

There are also some pre-loaded configurations located in the dots directory.

• Trim down the image. The generated iso is about 6.5G now. Maybe extend the trim.sh script?
• See if the process of creating ISO (with cubic) can be automated. See context.
