Description Pat Riehecky 2022-09-14 13:37:21 UTC

Description of problem:
When WatchdogDevice=/dev/watchdog systemd still attempts to open /dev/watchdog0.  For reasons I don't understand, my host doesn't have /dev/watchdog0.

As a result, the watchdog is not initialized or managed by systemd.

Version-Release number of selected component (if applicable):
systemd-250-11.el9.x86_64

How reproducible:
100%

Steps to Reproduce:
1. Set WatchdogDevice=/dev/watchdog
2. reboot
3. if system doesn't have /dev/watchdog0 the watchdog is not initialized
4. if system has /dev/watchdog0, it is used instead of /dev/watchdog

Actual results:
The WatchdogDevice setting isn't honored.

Expected results:
The config option should be honored
