[PATCH BlueZ 0/1] Enable D-Bus activation of bluetooth.service

[PATCH BlueZ 0/1] Enable D-Bus activation of bluetooth.service

[Grant Moyer]

D-Bus can automatically launch programs on demand when a message is sent to their bus name. Bluez provides src/org.bluez.service for this purpose, but it writes "dbus-org.bluez.service" for the Systemd service name, while the Systemd service is actually named bluetooth.service (generated from src/bluetooth.service.in). The Systemd service defines an alias named dbus-org.bluez.service, but Systemd aliases only come into effect once a unit is enabled.

Effectively, this means that instead of launching bluetoothd on demand whenever it's requested, D-Bus activation is only used if the service is enabled but happens to not be running, such as the first time it's enabled or if it crashes.

[PATCH BlueZ 1/1] org.bluez.service: enable D-Bus activation of bluetooth.service

[Grant Moyer]

D-Bus was configured to activate dbus-org.bluez.service, which is only
an alias for bluetooth.service, and so isn't resolvable unless the
service is already enabled. This means D-Bus cannot launch bluetoothd
on demand in most cases (for example when running bluetootctl without
the bluetoothd systemd unit configured to run at startup). This changes
the D-Bus configuration to activate bluetooth.service itself, so that
bluetoothd can be launched by D-Bus on demand.

Which would mean that bluetoothd would get started on system where it
is disabled, but somebody runs bluetoothctl as you mention?

Then that's a no. We do not want bluetoothd to get started unless the
system configuration says that bluetooth.service is enabled. Otherwise
it effectively makes it impossible to disable bluez without
uninstalling bluez, which is very very complicated for integrated
desktops.
