Bluefin is an immutable OS. Updates work differently from traditional Linux: the base image is updated atomically via OCI pull; applications (Flatpaks, Homebrew) update independently.
Load with: point your agent at this file.
Bluefin has three independent update layers:
| Layer | Tool | When Applied |
|---|---|---|
| Base OS image | bootc / rpm-ostree | On next reboot |
| Flatpak apps | flatpak update | Immediately |
| Homebrew packages | brew upgrade | Immediately |
# Check for a pending update (non-blocking)
bootc status
# Pull latest image (runs in background, applied on next reboot)
# This happens automatically — you rarely need to run this manually.
ujust update
# See what changed in the staged image
rpm-ostree db diff
# Reboot to apply the staged update
systemctl reboot
# Roll back to the previous image (takes effect on next reboot) — preferred
bootc rollback
# Legacy/Fallback (pre-bootc systems): rpm-ostree rollback
# rpm-ostree rollback
# Or from GRUB: select the previous entry at boot
flatpak update
brew update && brew upgrade
# Show current and staged image info
bootc status --json | jq '{booted: .status.booted.image.image.image, staged: .status.staged}'
# Show last update time
rpm-ostree status
Bluefin automatically applies image updates in the background. Flatpaks also update automatically via a systemd timer. Manual intervention is only needed if you want to force an update immediately or roll back.
