systemd weewx V5 using mysql waits for mysql to start

[Greg]

I am using weewx V5 and also using msql (mariadb) and after a reboot weewx has to wait until mysql starts.

I have added After=time-sync.target mariadb.service to the systemd service file.

Could this be added to the weewx-data/util/systemd/weewx.service file maybe as a comment for other users of mysql?

Yes. Good idea.

However, I'm not sure that these databases routinely install with a systemd service file. For example, the machine I'm working on now uses a /etc/init.d file for MySQL.
