[digikam] [Bug 377587] The --database-directory argument should also be the location of the digikamrc file when used

[Simon Frei]

Thanks for the clarification, I get your scenario now. So it is a
trade-off between no side-effects and data safety. I still think that a
user using the command line options should be aware of the difference
between config and database and therefore be in charge of using
sensible/safe options. However planning for the DAU is also a good idea.

I would like to hear what Gilles/Maik/Mario/... think about this.
Recap: The question is which of these options is favourable (arguments
in the comments above):
1. Set config to the same directory as --database-directory. If no
config file exists there, create a new one/copy over the default one
(still respecting --config if given).
2. Always use the default config unless --config is given, also with
--database-directory.
