I believe you do not need to be concerned. The design of Linux in general is to manage log files in a way that does not exhaust the storage available. Spurious data in logs does use up space, but I did not suggest there was a crash problem solely due to log utilization. Logging is a good thing; zeroing log files is an unnecessary and forensically destructive practice.
In DSM, syslog events are logged by default to /var/log/messages. Each Linux installation has syslog rules that split off certain logs to other files. There are also multiple ingress points. Kernel events, for instance, are independently logged to the kernel log and the syslog default.
There are a number of unimpactful, essentially useless, and unmanageable error logs due to unsupported system events in XPEnology. My intention was solely to improve the signal to noise ratio in the log files (make them more useful) by suppressing those types of logs.
