ipsilon-server-install sometimes fails to log & emit errors
    
    ipsilon-server-install may silently and immediately fail, nothing is
    emitted to the console nor captured in the log file, it's just a
    silent complete failure.
    
    An example that reproduces the problem is a hostname without any dots
    in it, e.g. "localhost".
    
    The log level is set after some code executes (e.g. arg parsing).
    If that code raises an error the exception handler will log it
    at the debug level, but because the log level has not been set
    yet to debug (it's still at the default error level) the message
    is not emitted.
    
    The log level should be set as soon as logging is initialized.
    
    An error message should be emitted to the console, therefore in
    additon to the exception handler logging the error to the debug log
    along with the stack trace it should also emit just the message to the
    console.
