I see this problem in the uclibc version:

```
$ kubectl run -it --rm evanstest-b5 --image=busybox:1.32.0-uclibc -- sh
If you don't see a command prompt, try pressing enter.
/ # nslookup opentelemetry-collector.observability.svc.cluster.local
Server:         10.0.0.10
Address:        10.0.0.10:53

*** Can't find opentelemetry-collector.observability.svc.cluster.local: No
answer

/ # 
```

The musl and glibc versions partially work:

```
$ kubectl run -it --rm evanstest-b3 --image=busybox:1.32.0-musl -- sh
If you don't see a command prompt, try pressing enter.
/ # nslookup opentelemetry-collector.observability.svc.cluster.local
Server:         10.0.0.10
Address:        10.0.0.10:53

If you don't see a command prompt, try pressing enter.

The Kubernetes community has been working around this issue for a couple of
years by pinning to busybox:1.28 - what can we do to help fix this issue?
