31 * State machine for mounting. |
|
32 * |
|
33 * This state machine assumes that connection awareness is off. |
|
34 * In "connection awareness" error state for mounting is quite different, |
|
35 * as failure to connect to the server is not considered to be fatal, |
|
36 * but instead puts the engine to disconnected mode. |
|
37 * Feasible strategy is probably to create an alternative initial state |
|
38 * with a different ErrorL, set if connection awareness is on. |
