# Services
|
|
|
|
## 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. All 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 must not be
|
|
blocked. A service may be blocked for several reasons:
|
|
|
|
- The user has manually stopped the service using `initctl stop
|
|
JOB`.
|
|
|
|
- The binary repeatedly dies after being started. I.e. keeps
|
|
crashing.
|
|
|
|
- The binary is missing in the filesystem.
|
|
|
|
* `C`: Service conditions are satisfied.
