[Bug 1582707] Re: Watchdog package installation is unclear/flawed

[Andrew Dittes]

I ran into this issue today, and at the very least it is a documentation
issue.

The only way I've found to get watchdog running on startup is to modify
watchdog.service.

I found instructions on how to do this here:
https://kd8twg.net/2015/10/30/raspberry-pi-enabling-watchdog-on-
raspbian-jessie/

Basically you just need to add the following lines to
/lib/systemd/system/watchdog.service:

[Install]
WantedBy=multi-user.target

After that, systemctl enable watchdog.service works as intended.

However, it doesn't seem right that you should modify a system file to
get it to start correctly. If there is a better way to start watchdog,
it should be documented somewhere. Otherwise, should I create a patch to
add this change? Or would it be better to report this to Debian?

Title:
  Watchdog package installation is unclear/flawed

Status in Raspbian:
  New
Status in watchdog package in Ubuntu:
  Confirmed

Bug description:
  The watchdog package does not allow a persistent installation across a
  reboot using the systemV way of doing things in Jessie Lite
  (2016-03-18) anymore. The installation messages of the package shown
  on the console are confusing and do not point to solutions. The only
  way to get it working across a reboot now is to use rc.local or cron.
  That is a kludge at best, so what is the correct installation
  procedure now.

  Trying to install watchdog the systemd way is also not working.
  Although the systemd service files for watchdog and wd_keepalive are
  installed, they do not work without changes and there are no pointers
  offered to lead to a proper installation.

  I wrote a post on the Raspberri Pi forum that details the problems
  with the messages and the installation issues.
