Yes I have this concern too. jackdbus is controled by using jack_control 
or dbus directly for which there is no documentation besides the source I 
would guess. US_controls uses jack_control right now (which also has no 
documentation) and by running jack_control with no parameters one gets a 
list of commands some of which will tell you what some other commands 
might be. None of them that I could find will set logging levels. The next 
version of US_controls will use logrotate to help keep the log files from 
getting too big. You may want to set up a cron job to do this for you 
until that release. It would be possible to use jackd instead of jackdbus 
but that would just mean the the US_controls log would start to grow 
quicker instead because jackd logs to stdout and stderr.

So the answer is that while jackdbus seems to provide no way of doing 
this, logroatate is already installed and gets run by cron once a day (I 
think) by the system. However, because your log file is in userland you 
would be better off running it from the user crontab with it's own config 
file.
