upsd sends a message to syslog for each and every upsc connection that is made to it. When using upsc for monitoring, this creates _a lot_ of noise in /var/log/messages. Could we please have a patch in the package until this is fixed upstream?
Logging of upsd connections is quite an understandable feature for security reasons (among others). There is upsmon that can shut down the machine or notice users on power events. The required change was not made in upstream nut AFAIK. For these reasons I'm against removing the logging.
