[Kea-users] ISC-KEA with MariaDB on Debian Buster Startup Sequence

[perl-list]

I don't know for sure as I have so far managed to largely avoid "systemd" but do have some small experience with it.

radiusd.service on one of my servers has this:

After=syslog.target network-online.target ipa.service dirsrv.target krb5kdc.service mysql.service mariadb.service postgresql.service

meaning all of those  .target or .service files would need to finish before it starts radiusd.service

You can probably tailor your After= line to be more relevant to your configuration.

Someone correct me if there is a better way.
