Usually is expected to have the default config as deployed by install (in /etc/ or /usr/local/etc) when running a globally deployed kamctl or by presence in source three when running a devel environment, plus user specific options (e.g., user/password for database) in a user home config
I can understand that. I'm not against that of course. Maybe better documentation of how `kamctl` loads its configuration and order would be the best then. ie [(main documentaion](https://www.kamailio.org/wikidocs/tutorials/getting-started/main/#tools) of `kamctl` does not provide any information other than `kamctl` loads its config from `kamctlrc` found in same folder of `kamailio.cfg`). When first read that, I made the assumption that only one file is loaded, but after checking the source code that is not the case.
I may also have missed something in other documentation pages, so please point them to me if you happen to have one.
