That's possible. I think it is more likely that the hook script isn't
able to figure out what to override it with for this case and so does
nothing. Similar to #5910156.

It should work due to the initrd override, that override exists exactly
because root=/dev/ram is the default on qnap (and other) devices, and
most people don't have a console cable to mess with it.
