Cross-distro coverage
RPM: dbus-daemon (Fedora) · PAC: dbus (Arch) · DEB: dbus (Debian/Ubuntu). Full parity — same DBUS_SESSION_BUS_ADDRESS env, same supervisord fragment, identical behavior downstream.
Usage
# image.yml -- now included in all images with supervisord
my-image:
layers:
- dbus
ov eval dbus Integration
The ov eval dbus command provides native Go D-Bus interaction with containers via godbus/dbus/v5. It operates in two modes:
- Remote mode (
ov eval dbus notify myimage "title" "body"): delegates to the container'sovbinary viaengine exec container ov eval dbus notify . "title" "body". Falls back togdbus callifovbinary is not in the container. - Local mode (
ov eval dbus notify . "title" "body"): connects directly to the local session bus. This is what runs inside the container when delegated from the host.
Commands
ov eval dbus notify <image> "title" "body" # Send desktop notification
ov eval dbus list <image> # List D-Bus services
ov eval dbus call <image> <dest> <path> <method> [type:value...] # Generic method call
ov eval dbus introspect <image> <dest> <path> # Service introspection
Notification Delivery Chain
ov cmd/ov tmux cmd/ov eval record cmd → sendContainerNotification() → ov eval dbus notify → org.freedesktop.Notifications.Notify → swaync/mako → desktop popup
For notifications to work, the image needs:
dbuslayer — D-Bus session bus (this layer)swaynclayer — notification daemonovlayer — in-container ov binary for native D-Bus (falls back togdbusfromglib2)
Error Messages
ov eval dbus provides explanatory errors when D-Bus is unavailable:
- No session bus → suggests adding the
dbuslayer - No notification daemon → suggests adding
swaync - No
ovbinary → falls back togdbus, warns about addingovlayer
ov status Probe
The dbus probe checks:
- Whether
dbus-daemonprocess is running - Which notification daemon is active (swaync, mako, dunst)
Shows as dbus:ok (notify:swaync) in ov status detail view.
Used In Images
- Transitive dependency via
swayin all desktop images - Now explicitly added to all images with supervisord (openclaw, jupyter, ollama, immich, etc.)

Use when authoring or modifying a charly PLUGIN — a candy with a `plugin:` block that contributes Providers (verbs/kinds/deploy-targets/steps/builders/commands), its own CUE schema, builtin (compiled-in) or external (out-of-tree git repo). Covers the unified Provider model, the per-plugin CUE-schema contract (single source → Go params for dev + schema-over-Describe RPC for runtime), the SDK, and the loader.

The CUE data-validation / configuration CLI (cue), pinned to v0.16.1. Use when working with the cue candy, installing the cue binary into a box or onto a target:local dev host, or running the offline schema-vendoring pipeline that feeds charly's egress validation.

CUE EGRESS validation — validating (and, where it adds value, generating) the config files charly WRITES to a system BEFORE the bytes hit disk. MUST be invoked before working on charly/egress.go, the vendored schemas under candy/plugin-egress/egress-schemas/vendor/, the ValidateEgress / registerVendoredEgressKind path, the offline `task cue:vendor` pipeline, or adding an egress schema for any written artifact (cloud-init, k8s manifests, traefik routes, runtime config, install ledger, systemd/quadlet units, ssh_config, libvirt XML).
