I'm not sure if it is optimal solution, but I'll play along. Any
recommendations for default value for that parameter?

The problem I have with exposing this to user configuration is that if
the user changes the directory, suddenly server will loose its server
identifier after next restart. This would in turn cause server to
reject existing clients' requests (because of server-id mismatch). But
that problem can be solved by writing existing server-id to the new
directory if it changes.
