You are right: using HUP through newsyslog(8)'s pid_file field is a better approach than suggesting a graceful restart or shutdown for log rotation. I had missed that i2pd handles log reopening this way, and the additional tunnel config reload / transient key rotation side effect is useful too. The corrected README section would look like this: ``` Logging ======= By default, the OpenBSD port of ${PKGSTEM} sends its log messages to syslogd(8), which writes them to the /var/log/daemon file. The default log level of ${PKGSTEM} ("warn") can be very verbose. You may want to reduce this log verbosity by changing the "loglevel" parameter in /etc/i2pd/i2pd.conf. If you want log messages to be written to another file, e.g. /var/log/i2pd/i2pd.log, you can change the "log" and "logfile" parameters in /etc/i2pd/i2pd.conf. To have this log file rotated automatically, add an entry to /etc/newsyslog.conf using the i2pd pid file so newsyslog(8) can send SIGHUP to the daemon after rotation. For example: /var/log/i2pd/i2pd.log _i2pd:_i2pd 644 6 * $D13 Z /var/i2pd/i2pd.pid Sending SIGHUP is enough for log rotation, and also makes i2pd reload its tunnel configuration and rotate transient keys. ``` Thanks again for the correction and for testing this in your install.
