About & Inspirations

My spin based on Fedora Silverblue, which is derived from the amazing Universal Blue project. This image is created with BlueBuild tooling for making & maintaining container-based Linux desktop images.

cabos is inspired and borrows heavily from Bluefin-DX and gidro-os.

The main idea is to have an up-to-date, stable, and pre-configured base OS, and to use customized containers with Distrobox to do development work within it. You can see an example of a base Ubuntu container to get started with here.

ZSH is configured to use oh-my-zsh by default, but customizing the config has changed a little. If you use an Distrobox based on Jetskis, you can share zsh between the two, but also have seperate options as well:

By default, your new .zshrc config for your machine will be located at ~/.config/contexts/localhost/.zshrc. The default config for each Distrobox will be located in ~/.config/contexts/container-name/.zshrc. To have shared config across both localhost and Distrobox containers, create a new config ending in .zsh here: ~/.config/contexts/config.d/. Please note, it is not recommended to modify the base ~/.zshrc file since it will source the appropriate files for whatever you're running at the time.

Running SETUP_DEV_TOOLS=true distrobox enter jetskis will setup nvm and pyenv in your container. You can modify the ~/.zshrc file if you want to install other packages.

Installation

ISO (Recommended)

ISOs are online-based & are constantly upgraded. There is no need to worry about the version & the date of the ISO.

ISO is available for download here.

Just download & proceed with installation.

After you get into the OS, type this command into Terminal & reboot:

rpm-ostree rebase ostree-image-signed:docker://ghcr.io/jitcos/cabos:latest

Rebase from Silverblue

To rebase an existing Silverblue/Kinoite installation to the latest build:

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

  rpm-ostree rebase ostree-unverified-registry:ghcr.io/jitcos/cabos:<version>
  

• Reboot to complete the rebase:

  systemctl reboot
  

• Then rebase to the signed image, like so:

  rpm-ostree rebase ostree-image-signed:docker://ghcr.io/jitcos/cabos:<version>
  

• Reboot again to complete the installation

  systemctl reboot
  

This repository builds date tags as well, so if you want to rebase to a particular day's build:

rpm-ostree rebase ostree-image-signed:docker://ghcr.io/jitcos/cabos:20230403

Modifications
