Actually it does a bit more than that, but the bottom line is that (for
scripts that source /lib/lsb/init-functions, which every init script in
Debian is supposed to do) /lib/lsb/init-functions.d/40-systemd ensures
that "/etc/init.d/<script> <action>" is redirected to
"systemctl <action> <script>.service" for the common values of <action>,
i.e. start, stop, restart, reload, force-reload, status. This is
usually what you want, but there is a magic environment variable that
lets you skip the redirect.

Use "_SYSTEMCTL_SKIP_REDIRECT=true /etc/init.d/<my own daemon> status",
and your init script won't redirect to systemctl.
