With the recent changes to the condition handling it has become more and more evident that the canonical reference for a task/run/service is the NAME:ID representation. Up until now we've kept the older JOB:ID for some sort of compatibility fallback. This patch removes the support to simplify maintenance going forward.

State Machine
|
|
-------------
|
|
|
|
A service is bound to a state machine that is in one of six (6) states.
|
|
For `run`s and `task`s there is an additional end state called `DONE`,
|
|
not shown in the diagram for brevity. Services start in the `HALTED`
|
|
state.
|
|
|
|
The current state depends on the two following conditions:
|
|
|
|
* `E`: Service enabled. In order for `E` to be satisfied, the service
|
|
must be allowed to run in the current runlevel and not be stopped.
|
|
|
|
A service may be stopped, or blocked, for several reasons:
|
|
|
|
- The user has manually stopped the service using `initctl stop NAME`
|
|
- The program exits immediately. I.e. keeps crashing (make sure to use
|
|
the 'run this service in the foreground' command line option)
|
|
- The binary is missing in the filesystem
|
|
|
|
* `C`: Service conditions are satisfied:
|
|
|
|
- `on` (+): The condition is asserted.
|
|
- `off` (-): The condition is deasserted.
|
|
- `flux` (~): The condition state is unknown.
|
|
|
|
