Hi Paul,
The problem here is that the /etc/rc.d/newsyslog script is used to
initialize the system at boot time with missing log files specified by
/etc/newsyslog.conf and not do any log rotation. The arguments passed
to that invocation of newsyslog are (by default):
- -C If specified once, then newsyslog will create any log files
which do not exist, and which have the C flag specified in their
config file entry. If specified multiple times, then newsyslog
will create all log files which do not already exist. If log
files are given on the command-line, then the -C or -CC will
only apply to those specific log files.
- -N Do not perform any rotations. This option is intended to be
used with the -C or -CC options when creating log files is the
only objective.
Because -N is not used under normal circumstances, but should be used at
boot time, you would need two different specifications for newsyslog
flags in /etc/rc.conf, one for boot time and one for invocation from cron.
That would complicate the rc system somewhat, so I would lean toward
simply adding your preferred arguments to the crontab file. I modify
the system crontab file on my machines, and I don't think there's a big
problem doing that.
Regards,
Greg
