Custom OS for Programming Contests

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

Installation

You can go two ways about this:

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

Prepare custom ISO with Cubic

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

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

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

Customize an existing installation

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:

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

What's inside?

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.

TODO

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.
