What does the /etc/sysconfig/network-scripts/ do?

I'm using CentOS 6.8 but think this is a more general Linux question.

I'm writing a script which modified the hosts file in /etc but have noticed there is another hosts file in /etc/sysconfig/network-scripts/

I've had a search but can't find a description for the use of this host file, does anyone know? I'm trying to work out if I need to change multiple files.

This is not generic for Linux, just for the RedHat family.  (RHEL, CentOS, Fedora, and reivatives thereof).
the files in that directory are scripts that  configure the network.
Part is infrastructure, (ifup/ifdown) with support for various technologies. and ifcfg* script that configure interfaces.
(The ifcfg ones just contain symbol assignments and are sourced)

On a system i manage there is no hosts file there...
Any clue on it's contents?

We have a setup where we have over 100 profiles in /etc/sysconfig/networking/profiles and each profile has its own hosts file which overwrites etc/hosts when its applied.

I just noticed the hosts file in /etc/sysconfig/network-scripts/ wasn't getting updated when we changed profiles. Looks like its maybe a leftover from the guys who used the laptop before I got hold of it.

Thanks for looking into this for me noci
