Maybe this is not necessary to be covered in kdumpctl manpage. Declare that we only support systemd wdt interface somewhere should be enough.
I remember vaguely that I had got comment for RFC patch to include these information in man page. Yes, if we limit to systemd support only then it will be easier. But where to put that information other than man page.
Maybe add one section in the howto.txt about the wdt notes should be fine.
Thanks Dave
Systemd wdt will always run before kdump service?
Yes,
