Atomic Centos - no wget

does come with curl though - so this line works

```
curl -s -o /dev/null -O /etc/nodequery/nq-agent.log -m 25 -X POST -d "$data_post" -k "https://nodequery.com/api/agent.json"
```

just installed manually - followed the install script and figured out what files and crontab was needed
