Unfortunately, this option fails to work with "bos getlog" and does
nothing for the sites that wish to use use file logs.  Periodic restarts
is really not a desirable recommendation.  While I believe that
defaulting to syslog probably is the right way to go, I think we need to
consider the impact on documentation and end user best practices.

At the very least I believe that we need to implement an internal log
rollover mechanism based on either max size or max time with a max
number of old logs to be maintained.  Implementing this should not be
overly complicated if we agree that this internal file logging is not
meant to replace full featured log rotation tool chains.
