A command-line tool for building consistent, customized Raspberry Pi SD card and SSD images with automated configuration.
sdm is a command-line tool designed to automate the creation and customization of Raspberry Pi SD card and SSD images. It solves the problem of manually configuring multiple Pi systems by providing a consistent, repeatable process for installing software, setting system preferences, and applying personal customizations. This ensures every Raspberry Pi boots with a fully configured environment, ready for immediate use.
Raspberry Pi enthusiasts, developers, and system administrators who manage multiple Pi systems and need efficient, reproducible image building. It's ideal for those deploying Pis in clusters, educational settings, or IoT projects where consistency across devices is critical.
Developers choose sdm for its automation capabilities and plugin extensibility, which significantly reduce setup time compared to manual configuration. Its unique selling point is the ability to create identical, customized images with a single command, supported by a rich plugin ecosystem for advanced features like VNC setup, hotspot configuration, and disk encryption.
Raspberry Pi SD Card Image Manager
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Automates keyboard, locale, timezone, WiFi, and SSH setup by copying settings from the host system, as shown in the ezsdm example, ensuring every Pi boots identically configured.
Offers a plugin architecture for adding features like VNC setup, hotspot configuration, and app installation, with documented plugins such as 'apps' and 'vnc' for easy customization.
Allows near-online management of already-burned SD cards via --explore, enabling tasks like password resets or package installs without reimaging, as highlighted for recovery scenarios.
Supports automatic encryption of root and data partitions with minimal commands, enhancing security for Raspberry Pi deployments, as mentioned in the features list.
Limited to Raspberry Pi hardware and RasPiOS/Debian-based systems, making it unsuitable for other SBCs or operating systems without significant modification.
Requires comfort with Linux CLI and scripting; the README assumes familiarity with tools like journalctl and manual plugin editing, which can be a barrier for GUI-oriented users.
Default installation uses curl | bash from a remote source, posing potential security issues if not verified, though the README offers a download-and-inspect alternative.
Advanced customizations demand plugin programming or batch script writing, and the extensive documentation might overwhelm users seeking quick, simple solutions.
