Combining Features

Features can be combined freely:

Create a development workstation with:
- Desktop (GNOME)
- Docker
- CUDA for ML development
- SSH for remote access

Some features have dependencies:

• desktop requires either Ubuntu or Debian base
• cuda requires gpu-nvidia
• kubernetes benefits from docker (but works standalone)

Feature Conflicts

Certain features are mutually exclusive:

OpenFactory will warn about conflicts during recipe validation.

Custom Packages

Beyond features, you can request specific packages:

Also install: htop, vim, tmux, curl, jq

OpenFactory will add these to the build configuration.
