Removal of rsyslog

If rsyslog is no longer needed (mark package install as auto to find out).

Make sure systemd journal is persistent if that is what you want.

Check folder /var/log/journal/*/ to verify.

Then the following old log files can be removed too.

rm /var/log/auth.log*
rm /var/log/cron.log*
rm /var/log/daemon.log*
rm /var/log/debug*
rm /var/log/kern.log*
rm /var/log/lpr.log*
rm /var/log/mail.err*
rm /var/log/mail.info*
rm /var/log/mail.log*
rm /var/log/mail.warn*
rm /var/log/messages*
rm /var/log/syslog*
rm /var/log/user.log*
