Last night, Canonical released the first snapshot of its upcoming operating system, codenamed Resolute Raccoon. The list of available distributions in the WSL project's repository traditionally includes only stable, long-term supported versions of Ubuntu. 26.04 will be an LTS, and it will be added to the list in April next year, after the official release.
The network is the largest part of the .wslconfig configuration in terms of the number of parameters, so I decided to split the topic into several parts. In this part, I will review the main settings, and in the next, the additional and experimental ones.
If the .wslconfig configuration file is not created with explicitly defined settings, WSL 2 allocates hardware resources automatically. It uses all available CPU cores, half of the available memory, creates a dynamically expanding 1TB disk for instances, a shared swap file, and enables GPU support. This is sufficient for basic operation, but more fine-tuning may be required, especially for resource-intensive tasks. I prefer to allocate resources more precisely for my tasks and explicitly define all configuration parameters.
While going through old materials previously posted on Reddit, I came across a post about a WSL instance starting on its own. Today, I decided to update and repost it.
In parallel with writing new posts and developing the website, I continue working on WSL configurations. I collect, test, and document settings, gradually publishing them in the wsl-configs repository.
