# Choosing an OS for Raspberry Pi alternatives: vendor images, Armbian support levels, mainline

> OS support decides how usable an alternative board is. Compare vendor images, Armbian (with Standard, Community maintained and Staging support levels) and mainline distributions, and check the kernel's age before deploying long-lived IoT devices.

On a Raspberry Pi, the OS question is mostly solved. On alternatives it's the **main risk**: an IoT device runs for years and needs security updates the whole time.

## Three sources of images

| Source | Typical kernel | Pros | Cons |
|---|---|---|---|
| **Vendor image** (Orange Pi OS, Radxa, Banana Pi, Hardkernel images) | vendor (BSP) kernel | all board features (NPU, video, camera) often work first here | kernel can be old; update cadence depends on the vendor |
| **Armbian** | per board; vendor-derived or closer to mainline | consistent tooling across many boards, active community | support level differs per board (see below) |
| **Mainline distribution** (Debian, Fedora, etc. on well-supported SoCs) | upstream kernel | long-term security updates, standard tooling | newest SoCs may lack drivers for NPU, video or some I/O |

## Armbian support levels (from Armbian's rules)

| Level | What it means |
|---|---|
| **Standard support** | Armbian publishes *stable* images through its mirrors and runs best-effort automated hardware tests; the board has an active maintainer |
| **Community maintained** | not under active supervision; images are **untested**, and the Armbian team won't respond to issues or apply fixes |
| **Staging** | work in progress; periodic/nightly CLI images, best-effort support |
| **Platinum** | business arrangements with vendors |

Before choosing a board, look it up on Armbian's download page and note its level. "An image exists" is not the same as "supported".

## Checklist for long-lived IoT deployments

1. Which kernel version does the image ship, and when was the image last updated?
2. Does the image receive **security updates** through the package manager, or do you have to reflash?
3. Do the features you need (NPU, hardware video, camera, PCIe/NVMe boot) work **on that image**, not just on the vendor's demo image?
4. Can you reproduce the image (build scripts, config) if the vendor disappears?
5. Plan updates: A/B root filesystems or at least tested backup and restore before running `apt upgrade` in the field.

## Claims

- Armbian publishes stable images for boards with Standard support and runs best-effort automated testing of basic hardware functionality. (unverified)
- For Armbian boards marked Community maintained, images are untested and the Armbian team does not respond to problems or apply fixes. (unverified)
- Armbian's Staging level is for boards not yet ready for stable releases; nightly or periodic CLI images are published with best-effort support. (unverified)
