systemd - Enable syslog

# Edit /etc/systemd/journal.conf and set the following options to prevent the creation of .journal files and to forward messages to syslog:
Storage=none
ForwardToSyslog=yes

# Check if syslog.service is a sym-link to /dev/null and remove it if so
$ ls -l /lib/systemd/system/syslog.service
$ rm /lib/systemd/system/syslog.service

# Unmask the syslog service so that it can be started
$ systemctl unmask syslog.service

# Start the syslog service (or just reboot)
$ /etc/init.d/syslog start

# All system messages should now show up in /var/log/messages
$ tail /var/log/messages
