[Debian-ha-maintainers] Bug#862248: No straightforward and permanent way to disable DRBD autostart, no drbd systemd unit file

[Christian Balzer]

Package: drbd-utils
Version: 8.9.5-1~bpo8+1
Severity: Important

Jessie (backports), systemd.

When running DRBD with pacemaker it is recommended (and with systemd
required, see link below) to disable DRBD startup at boot time.

However:
---
# systemctl disable drbd
drbd.service is not a native service, redirecting to systemd-sysv-install.
Executing: /lib/systemd/systemd-sysv-install disable drbd
insserv: warning: current start runlevel(s) (empty) of script `drbd' overrides LSB defaults (2 3 4 5).
insserv: warning: current stop runlevel(s) (0 1 2 3 4 5 6) of script `drbd' overrides LSB defaults (0 1 6).
---

But since systemd-sysv picks up anything in /etc/init.d/ we get after a
reboot:
---
# systemctl status drbd
  drbd.service - LSB: Control drbd resources.
   Loaded: loaded (/etc/init.d/drbd; generated; vendor preset: enabled)
   Active: active (exited) since Wed 2017-05-10 10:37:39 JST; 6h ago
     Docs: man:systemd-sysv-generator(8)
   CGroup: /system.slice/drbd.service
---

Ways forward would be a unit file for systemd that actually allows disable
to work as expected or some other means to (permanently) neuter the init.d
file (instead of an "exit 0" at the top which did the trick for now).
