Hadron is an independently developed Linux distribution designed as a minimal foundation for cloud and edge environments. It is built from scratch rather than being based on an existing distribution, and stays close to vanilla upstream components.
The distribution uses musl libc, systemd and vanilla Linux kernels. Hadron supports conventional booting with Dracut and GRUB as well as Trusted Boot using unified system images. System upgrades are handled using the Kairos agent, with an A/B approach that allows a new system image to be deployed while retaining the previous version for recovery.
Hadron does not ship with a package manager by default. Instead, it is intended as a small base system on which additional software and services can be built. Images can also be configured with k3s or k0s for Kubernetes deployments.

What's a Linux distribution ("distro")? |
| A distro provides the user with a desktop environment, preloaded applications, and ways to update and maintain the system. Each distro makes different choices, deciding which open source projects to install and provides custom written programs. They can have different philosophies. Some distros are intended for desktop computers, some for servers without a graphical interface, and others for special uses. Because Linux is an open source operating system, combinations of software vary between Linux distros. |
