$ sudo journalctl
systemd[1]: /lib/systemd/system/plymouth-start.service:16: Unit configured to use KillMode=none. This is unsafe, as it disables systemd's process lifecycle management for the service. Please update your service ...
systemd[1]: /lib/systemd/system/netdata.service:55: Standard output type syslog+console is obsolete, automatically updating to journal+console. Please update your unit file, and consider removing the setting altogether.
systemd[1]: /lib/systemd/system/netdata.service:56: Standard output type syslog+console is obsolete, automatically updating to journal+console. Please update your unit file, and consider removing the setting altogether.
I assume that the fix for plymouth-start.service is:
sudo sed -i "s|KillMode=none|KillMode=mixed|g" /lib/systemd/system/plymouth-start.service
for netdata.service is:
sudo sed -i "s|syslog+console|journal+console|g" /lib/systemd/system/netdata.service
