Why can't you have _host.example.com as an A record label? (It'll be slightly confusing since it'll be _host.example.com.yourdomain.name when fully resolved, but if that was your intent...)
In my experience there's very little that already-busy customer service reps can do when faced with the sort of socially deaf person who parks in an EV space. Tesco employees are always super-nice and do their best, but wilful ignorance in drivers is hard to correct :(
Some cheeky BMW oik ICEing an EV charge space at Gorton @Tesco in Manchester. This kind of thing irritates me immensely.
**AND** they were parked really badly (diagonally in the space)

&str and &[T] are Copy, but if you're into cloning then you probably want owned content not borrowed content. Owned strings are String not &str, and owned slices are Vec<T> not &[T]
If you have a &str or &[T] and you want an owned version then the ToOwned trait is your friend.
AFAICT (we borg quite a bit) this is because they make no guarantees as to how much of the repo they touch during a backup, and rsyncing during such an event might result in a broken 3rd strand. So long as you're careful to not hit that, you should be fine.
