Hmmm... newsyslog(8) has no intrinsic capability to label the backup
files it creates with the date.  It would be quite easy to write a
script that went round after newsyslog and renamed any backup log
files according to their last modification date, but that would mean
that newsyslog won't recognise the backup of the logfile when it comes
time to reclaim space in the partition.

You could insert the date into the file path by modifying /etc/crontab:

0 * * * * root d=/var/log/`date +%Y%m%d`; [ -d $d ] || mkdir $d ; newsyslog -a $d

but that still suffers from the problem of newsyslog(8) not being able
to remove the oldest backup files.

Also, take a look at the sysutils/cronolog port -- I don't think it
will help you very much with log files generated by syslogd(8) but it
works very well with apache and similar.

	Cheers,
