IS there a template for proxmox hosts file in containers?

[FrankB]

When proxmox create the hosts file inside a container it appears as:
192.168.0.1 ns1 ns1.domain.com

and I need it to appear as:
192.168.0.1 ns1.domain.com ns1

if not it throws off the hostname --fqdn command.

Please advise if there is a config file where I can change this.
