>Not sure what you mean by "declarative services" here?

Declarative syntax means you configure something using a bunch of
variables defined and curated by the program you're configuring. The
opposite of declarative syntax is imperative syntax, which is another
word for programming something.

For example, /etc/fstab is declarative, and the sysvinit init script for
dbus is imperative.

Sysvinit init scripts are imperative, not declarative. Systemd unit
files are declarative. /etc/fstab is declarative.
