BlueCat  

An opinionated tweaked ublue image based on silverblue-main.

What is this?

This is my own tweaked image deployment that I maintain for myself. It's mainly focused on graphics, programming and gaming workloads.

If anyone is using these images please reach out with a bug report so that I don't randomly change things on your computer.

How to use

The intended way to use this image is to use Flatpak for graphical apps and Homebrew for cli tools

Installation

1. You first need a Fedora Atomic Desktop installed.
2. Then you rebase with these commands

Tip

To install the Nvidia image just rename bluecat:latest to bluecat-nvidia:latest

• First rebase to the unsigned image, to get the proper signing keys and policies installed:

  rpm-ostree rebase ostree-unverified-registry:ghcr.io/polycatdev/bluecat:latest
  

• Reboot to complete the rebase:

  systemctl reboot
  

• Then rebase to the signed image, like so:

  rpm-ostree rebase ostree-image-signed:docker://ghcr.io/polycatdev/bluecat:latest
  

• Reboot again to complete the installation

  systemctl reboot
