In the end as you mentioned, it is up to you how you choose you log file
naming scheme.  Common sense is usually a good place to start, such as
avoiding logging kernel logs to a file called 'maillog.log' or

while others will use a different log file.

Of course I know that this is all up to myself to decide, but I would 
like to understand better what is the reasoning behind the various
