At least one file-based error log must be present.  In particular, 
it is used to redirect STDERR (as in some cases written to by 
various libraries), and it is also believed to be useful to log 
errors of writing to syslog when they happen.  If no file-based 
logs are configured, a compiled-in default one will be used.
