It is way too complicated. I want tools provided by the systemd people, not hacks.

Remember, I was simply commenting a feature that syslog has as default, and systemd refuses to implement.

I am using no scripting at all. I use the default toolset for handling syslog messages for decades of *nix.

/etc/rsyslog.conf:    (this configuration came with the system, commented out, so I just had to uncoment it)

news.crit                               -/var/log/news/news.crit
news.err                                -/var/log/news/news.err
news.notice                             -/var/log/news/news.notice
news.debug                              -/var/log/news/news.debug


/etc/logrotate.d/syslog:    (this configuration is the same as default for other files)

/var/log/news/news.crit /var/log/news/news.err /var/log/news/news.notice {
     compress
     dateext
     maxage 365
     rotate 99
     missingok
     notifempty
     size +4096k
     su news news
     create 640 news news
     sharedscripts
     postrotate
         /usr/bin/systemctl reload syslog.service > /dev/null
#       /etc/init.d/syslog reload > /dev/null
     endscript
}


#CER news.debug is very verbose, not needed to keep long.
/var/log/news/news.debug  {
     compress
     dateext
     maxage 30
     rotate 10
     missingok
     notifempty
     size +4096k
     su news news
     create 640 news news
     sharedscripts
     postrotate
         /usr/bin/systemctl reload syslog.service > /dev/null
     endscript
}
