// There are 4 sets of settings.
|
|
// - hard defaults - hardcoded in firmware, used for init defaults after flash or if stored data are corrupt
|
|
// - defaults - persisted by privileged user
|
|
// - current - persistent current config state, can be restored to defaults any time
|
|
// - live - non-persistent settings valid only for the current runtime
