This collection provides a comprehensive set of roles for configuring and managing Linux systems. While originally developed for the Mila infrastructure, most roles are designed to be environment-agnostic and can be used in any Linux environment. The collection is now open source to benefit the wider community.

The collection is designed to provide a standardized way to configure Linux systems, ensuring consistency across different machines and making system administration more efficient. While some roles may have Mila-specific configurations, contributions are welcome to make them more generic and adaptable to other environments.
