> Does PBS need `/etc/hosts`?

- PBS wants name resolution should be correct and work correctly ( /etc/resolv.conf should tell the where to check)
- [State-unknown,down - #12 by alexis.cousein](https://community.openpbs.org/t/state-unknown-down/2681/12)
- DNS services might fail or during power interrupt it might come up late , hence maintaining all the details of all the hosts of the cluster (same across server and compute nodes) in the /etc/hosts is the safest option
