“They” are me in this case, no shops have any space right now. But I just had a look at them, and it doesn’t look impossible… might be enough if I bang them a bit with a flathead, and then I can probably get them out with pliers. Finding imperial size hex bolts here in Europe will probably be harder 😃
Unbound is a recursive DNS, not an authorative. An authorative DNS server is needed for adding your own records. I suggest using bind, which can be both a recursive and an authorative.
