Offline installer

The rolling ISO embeds the local OCI payload, so the initial deployment does not need a registry pull. See the install section for USB imaging details.

Explicit opt-ins

xone driver is included, but Xbox Wireless Adapter firmware is never bundled; bluecat only downloads it after local user confirmation.

xone

Install

Fresh ISO install or signed rebase.

Use the ISO for a clean install, or rebase an existing Fedora Atomic / Kinoite-style system to the signed bluecat stream.

Install from ISO

Download the latest rolling installer ISO, verify it with the SHA256 checksum if possible, then write it to a USB drive with a normal image writer such as Rufus on Windows, balenaEtcher on macOS or Fedora Media Writer on Linux. Boot from the USB drive and follow the installer.

The ISO embeds the bluecat OCI image as an offline payload, so the initial system deployment does not need to pull the image from the registry. After installation, the system receives updates from ghcr.io/echocat/bluecat:44.

Rebase an existing system

Existing Fedora Atomic / Kinoite-style systems can use the signed rebase helper. Bootc-native systems can switch directly to the bluecat release image.

curl -fsSL https://raw.githubusercontent.com/echocat/bluecat/main/scripts/rebase-signed | sudo bash
sudo systemctl reboot

sudo bootc switch ghcr.io/echocat/bluecat:44
sudo systemctl reboot

Unofficial remix, clear boundaries.
