bluefin-common

Shared OCI layer containing common configuration files used across all Bluefin variants (bluefin, bluefin-dx, bluefin-lts).

What's Inside

This layer contains two main configuration directories:

/etc/ublue-os/ - System Configuration

• Bling - CLI theming settings
• Fastfetch settings - System information display configuration
• Setup configuration - First-boot and system setup parameters

/usr/share/ublue-os/ - User-Space Configuration

• Firefox defaults - Pre-configured Firefox settings
• Flatpak overrides - Application-specific Flatpak configurations
• Just recipes - Additional command recipes for system management
• MOTD templates - Message of the day and tips
• Setup hooks - Scripts for privileged, system, and user setup stages

Usage in Containerfile

Reference this layer as a build stage and copy the directories you need:

Copy everything:

FROM ghcr.io/ublue-os/bluefin-common:latest AS bluefin-common

# Copy all system files
COPY --from=bluefin-common /system_files /

Copy only system configuration:

This is what Aurora should use, gives shares the common set of files and keeps the images opinions seperate.

FROM ghcr.io/ublue-os/bluefin-common:latest AS bluefin-common

# Copy only /etc configuration
COPY --from=bluefin-common /system_files/etc /etc

Copy only the image opinion:

FROM ghcr.io/ublue-os/bluefin-common:latest AS bluefin-common

# Copy only /usr/share configuration
COPY --from=bluefin-common /system_files/usr /usr
