1description: > 2 Empty interface to indicate that the associated `Software.Version` should 3 prevent a state transition of the associated managed element while the 4 `Software.Version` is in `Activating` state. 5 6 The specific state transition(s) to prevent are left to the implementation. 7 A typical use of this would be to prevent (delay) the power-on of a managed 8 host while the BIOS is being updated. The managed host, via systemd 9 transitions, might start the power-on sequence and then wait for any object 10 with this `ActivationBlocksTransition` interface to no longer be in 11 `Activating` state. Causal ordering of dbus operations can prove that no 12 update is currently being performed and the power-on sequence may safely 13 continue. 14
