I agree that it makes sense to rephrase to avoid having to edit when
other parameters are added, and I'll send v6 in a moment. But regarding
the handle_boot_enabled, I think my patch set implements a superset of
that functionality (just set watchdog.open_timeout to 1ms), which is why
I asked Sebastian specifically to look at the patches, and he said that
they'd work for his use case as well. So while I personally don't really
care if both go in, it does seem a little silly and somewhat confusing
to have two parameters to do more-or-less the same thing.

Btw, where can I find the watchdog-next tree (or whatever it's called)
to see what is queued up?
