I am using Linode and every single time I boot my server, Linode (cloud provider) ovewrites the file below:
/etc/sysconfig/network-scripts/ifcfg-eth0
This is well documented and expected in order to keep the network interface working as expected. However sometimes I need to add configurations to this file and (of course) they are lost at next boot time. For example: I need to add the line below in the file:
ZONE="my_custom_zone"
And everytime my linode gets booted, this line is removed. So I am wondering: do you know any other place that I can insert this line to allow NetworkManager to read it everytime I boot my server? Is there somewhere else where I can insert the "eth0" (interface network name) configuration which works exactyl as if I had inserted in the file above?
