That's good, it is recommended to modify the command prompt

Sorry for the confusion, the -v in the service scripts stands for the option of output in VERBOSE level.

Actually, binary files are used to check version info instead of service scripts. I believe this change is doable.

agreed, this should be improved, maybe something like the daemon binary(binaries) version(s) to be returned in a service status query or from a new query option?
